Back in December, when I got my new (old) CD player, it didn’t come with either the remote or the owner’s manual. I could grab a copy of the horrificly scanned—and apparently only—PDF online, but I wanted a real, original, tangible manual. Fortunately, I located one seller who had a copy and I ordered it. A few days later the packet arrived, but he’d sent the Service Manual, an entirely different beast altogether. I emailed him and he wrote back, apologizing profusely and instructed me to instigate a return through eBay. I did as directed and got the return postage mailing label and my account was refunded.

I reached out to the seller a few days later and asked how I could pay for the manual since eBay had already refunded me. After several more days with no response I emailed him again. (This is a seller with a 99.5% positive feedback rating with whom I’ve done business before.) He wrote back and apologized again for the delay, telling me he was out of town and he would “try to find” the correct manual upon his return.

Another week passed and I heard nothing. So I wrote him again. He said he was having trouble locating it.

At this point I said fuck it, and told him not to worry about it. It was obvious he either didn’t have a clue where it was, or he was dealing with something personal that was preventing him from responding in a timely manner and to just forget about the whole thing.

No response. Of course.

Well, apparently this particular manual—much like the matching remote control for my unit—is rarer than proverbial hens’ teeth. I set a trigger on eBay to notify me if one ever showed up again and basically sulked off.

Today, I was attempting to locate the instructions in my desk folders for a CD Walkman I just put up for sale. And what should pop out?

My original instruction manual for the deck that I purchased in 1990!

There was obviously a reason the seller couldn’t find his copy.

Sometimes the universe smiles laughs at you.

In thanks, I’ve scanned this physical copy and upload it to the hifiengine.com repository so a good copy will be available to others.

And Revox, no less!

Peak 80s Sony

My holiday present to myself.

Okay, to most of you, this is just another piece of BPC [black plastic crap] from the early 90s, but to me, it’s an old friend. (And it’s not plastic; that’s an anodized aluminum faceplate and solid metal case.)

I bought this identical model back in July 1990 to replace my very first CD player that I got sometime in the mid 80s. How do I know the date? I was living in San Francisco at the time, I’d just gotten a mid-year bonus, and my mom was visiting. One day we went shopping and I came home with a new futon mattress (it was the 90s, after all), and this little gem.

It was my player for ten years or so and then it just disappeared. I don’t remember getting rid of it, but all of a sudden it was gone from the photographic record—along with my memory of what happened to it. At some point I think I must’ve pivoted to playing all my CDs through my DVD player and probably just felt that it was redundant and didn’t need it any more.

All I’m sure of is that it was gone by the time I moved back to Phoenix in 2002. At some point in 2003—after surviving seven weeks of radiation for my first cancer—I rewarded myself by returning to a dedicated CD player and then flipping units in and out of my system on almost a monthly basis trying to find digital nirvana (buying this shit used was still dirt cheap back then).

At some point between then and 2022 I got rid of my last CD player, only replacing it with a CDX-530 when I decided to get over myself and stop mourning the loss of my remaining discs. (I couldn’t find a CDX-730 at the time.)

When the 530 got too picky about reading discs, and my attempts to resuscitate it failed, I bit the bullet and bought a brand new player. It’s served me well over the past few years, and it sounded fine, but it never truly wowed me, y’know? It lacked the “personality” of those awesome 90s era machines, and since I really wanted a 730, I set a trigger on eBay to notify me whenever one was posted.

To be honest, the pickings have been slim since I first set that trigger. They don’t show up that often (I don’t know it’s because they’ve all died and been consigned to landfills, or if  they’re tanks and people hold onto them forever) but when they do show up they’re either listed as not working at all (after watching literally dozens of repair videos on these things, it might be a simple fix but I didn’t want to deal with it) or working but so beat up cosmetically they were an automatic pass.

Then a couple weeks ago I woke to an email that another had been posted and—though it was missing the remote control (a common issue)—it was pristine and working.

It arrived today. And yes, it works—and looks as good as it did in the seller’s photos.

And I have a secret to share: Yamaha hasn’t changed their CD remote codes in the last 40 years. While it would be nice to have the original remote that was paired with this player, they seem to be impossible to find, and pretty much any Yamaha CD remote will cover all the basic functions on any player. (As of this writing, I’m using the one from the new player I bought two years ago and it’s working fine, although I have ordered an era-appropriate remote so this one can go back with my 2 year old player should I decide to sell it.)

This set gave the 15-year-old me orgasms. Sadly, it was well outside my budget. (And still is!)

Beautiful. I’ve always admired this series; never enough to actually want to own one, but I can’t deny the attraction of the aesthetic Sony adopted here.

So I got my new tuner yesterday. (The component on the bottom for those of you who aren’t stereo geeks.)

It looked as good as in the seller’s pictures. Unfortunately it had a couple…issues.

First of all, I could not get it to tune in stereo. I mean I’ve never had great reception in this house, but the signal level was good on any station I tuned, and except for one brief instant, the red LED refused to trigger no matter what I did with the new coax antenna I bought for it. I considered running an outside antenna, so I ordered a 25′ coax cable thinking I could fish it through the old hole that had been drilled in the front wall for cable TV and reconnect the antenna outside.

Before I went to all that trouble (and realizing the cable I’d purchased (with already attached connectors) would not fit through the hole, I decided to just take the tuner outside and see if I could get stereo reception.

No joy. It didn’t work

The second issue was the battery-backed up memorized station feature. After the issues I’d had with my previous tuner, I figured an actual old-school battery backup would be a good thing, right? This being a fully analog tuner (not digital), the method for saving stations was rather ingenious for the time (1980-1982). The traditional tuning knob, in addition to being fully free-spinning was also motor-driven. You’d manually tune to a station, hit the memory buttons, and it would memorize the position and when you tuned to another station and wanted to go back to your memorized station the motor would engage and turn the knob back to where you set the memory.

Yamaha describes it thusly:

Well, that didn’t work either, but I wasn’t really surprised. This device was over 40 years old and unlike my other tuner which used a capacitor for backup, the NiCAD battery that powered the memory in the T-7 was undoubtedly shot.

Opening up the case, the battery was indeed shot; the contacts had corroded to such a degree that merely touching the soldered in battery sent it flying.

Undaunted, I knew this was merely a simple rechargeable NiCAD battery and all I had to do was figure out a way of attaching one back to the board now that the contacts had broken off.

I went onto everyone’s most hated online retailer and found a single cell battery case with wire leads. It arrived today, and after cleaning the board of corrosion, I soldered the leads into the holes left by the original contacts, inserted a rechargeable NiCAD, held my breath, and powered it up. It came on with no puff of smoke, so I figured that was a positive sign. I went about memorizing my three most-listened-to stations and…success!

Now about that stereo issue…

I know nothing about radio/tuners other than discovering when I was a kid if you go blindly turning those screw-like pots you can royally fuck things up.

Luckily I had the service manual for the T-7, and that limited my blindness. After marking positions of screws on the front-end of the tuner I slowly adjusted each in turn to no avail. I moved them all back to their original location and moved on to the VCO pot. Again, after marking it, all I did was insert the screwdriver and give it the tiniest of jiggles and voila! Stereo reception. It was just dirty…

So now I have a fully functional tuner. Electronics servicing is not going to become my retirement avocation, and I’m not going to strain my shoulder slapping myself on the back with two successful repairs, but damn…it does feel good to be able to fix this stuff.

And I have to say, now that it’s adjusted, I’m getting the best reception I’ve gotten through any vintage tuner or receiver I’ve owned int he last several years. With the local classical station in particular (always noisy) the background is dead silent.

We’ll see if everything is still working tomorrow. 😉

Last year I bought a vintage AM/FM tuner that matched my Yamaha amplifier. Seller of course said everything was working fine, and indeed it was—if you kept it turned on 24/7. Otherwise if you turned it off it would forget all it’s settings and memorized stations. Irritating, to say the least.

Now listen, Phoenix is a radio wasteland bearing little resemblance to the smorgasbord it was in the 70s and 80s (as I suppose most locations are these days). Still, I like to have a tuner around for the classical and the NPR/Jazz station. Six months ago the NPR/Jazz station announced they were dropping the Jazz altogether in favor or talking/babbling heads 24/7. They’d already cut back on the music to three nights a week from 8 pm to midnight, so this didn’t come as a compete shock…and they did still offer Jazz 24/7 on their HD2 station. (I can receive this in my car, thankfully.)

Apparently all Yamaha tuners of the period (mid 80s) have developed an issue with the “super capacitor” that keeps power trickling to the memory chip that retains all the settings when the unit is turned off. From what I read, swapping it out with a new one was a fairly simple procedure, but based on my track record of working with electronics—not to mention the amount of disassembly required to get to it and unsolder the thing from the back of the circuit board—it wasn’t something I was in any rush to tackle. So I disconnected it from the system altogether and put it away in a closet.

Well, bored out of my mind, I pulled it back out a couple days ago and did a run through of the disassembly and realized it wasn’t all that bad. So I ordered the necessary capacitor (actually two different physical designs to guarantee proper fit since the original was no longer readily available).

The new caps arrived today and after doing a test fit to make sure the legs lined up with the holes in the board, I desoldered the old one and soldered the new cap in place.

I put everything back together to a degree that I could test it, plugged it in, turned it on, and…no puff of smoke! Success! Everything seemed to work, and it was actually retaining stored stations again if you turned if off.

My only disappointment is that radio reception itself in this house is horrific and the standard wire ribbon antenna has never cut it…so I’m still a little disappointed. But I’m ecstatic that I fixed it.

But wait! There’s more to this story. Now that it’s working I’m actually going to turn around and sell it.

Why? Because I found a beauty—while a year or two older than my amp—that complements its design wonderfully. It’s old school with a motorized analog dial and while it has the option to store 5 stations in a memory chip on board, it’s got a battery backup (hard to tell from the pictures I’ve found, but apparently just a standard double-A cell) that will store the info for up to two months if the unit is unplugged.

I spotted it on eBay the other day, but got sniped in the last fifteen seconds by another bidder who was willing to pay way more than I was. But wouldn’t you know, I found another unit on Reverb for less than my maximum bid on the eBay unit. I turned around and then offered the seller $25 less than that and he took the offer and threw in free shipping. It should be here next week.

Picture it: Tucson 1986. Jerry’s Audio. A $2000 credit line.

I’d just bought a new system that included the sweet Yamaha A-700 amp that I’ve written about at length, a Yamaha T-700 tuner, a pair of Phase Tech PC-60 loudspeakers and a Sony D-10 portable CD Walkman. My old silver Sony cassette deck that I’d never been completely happy with stood out like a sore thumb in this stack of black anodized aluminum, so I went shopping.

I’d always wanted a Nak. At the time (near the height of the cassette era) Nakamichi was the undisputed king of the hill and prior to the widespread adoption of CDs, the recordings made on their decks were about as perfect copies of the original source material as you were likely to get. Like so many of my peers, I was big into cassettes (at one point having a couple hundred; all but a handful now long gone) that were perfect companions for my daily commutes.

And yet, standing there in Jerry’s, I was torn between the Nak 100 (in black, of course) and the Yamaha K-540 (also in black). The Nak had an edge as far as the specs were concerned, but I also knew I’d probably never hear the difference. They were approximately the same price.

Ultimately, I ended up going with the K-540 for the stupidest of reasons: I liked the physical design better. I stood there staring at the Nak, thinking there was just something off-putting about it—despite the company’s reputation for excellence—that 1986 me just couldn’t get over. The Yamaha seemed much more user-friendly—and it also had a LED tape counter.

Am I on the verge of getting back into cassettes? Oh hell no, Mary! As a teenager of the 70s, they always seemed magical, but oh, such a pain in the ass! Remember the BIC pen trick? Pulling a cassette out of a car stereo that had spilled its guts into the mechanism? (To this day I remember pulling a copy of Elton John’s Blue Moves that I’d recorded onto a C-120 blank—blanks you shouldn’t use for anything because the tape was so damn thin—because it wouldn’t fit on a C-90 out of my Mom’s car one afternoon.) Yeah, good times. Still, when I was at the height of using them on the daily—at the dawn of the (then) skip-prone portable CD revolution, they were still the best solution for popping in a Walkman and throwing in your bag for music on the go.

In 2025, MiniDisc remains my recording medium of choice, and at least for me it fulfilled Sony’s vision of replacing cassettes.

What led me down this rabbit hole today was stumbling across a repair video on YouTube of a guy diagnosing an inoperative Nakamichi 100 and I thought, those weren’t bad looking at all! You were a fool, Mark!

Normally when I’m in working at my desk, I’m listening to music through my headphones. It’s become a bit of a problem because the wired headphones I use—unlike my Bluetooth Airpods—do not have a pass-through option, so I’m effectively cut off from the outside world when I’m wearing them. Ben hasn’t said anything, but I know he’s becoming increasingly annoyed that I’m not responding to things he’s said—from the other room—simply because I can’t hear him. So, other than not listening to music while I’m working in the office when he’s home at all, I needed to find another solution. I could have gotten a plug-in bluetooth transmitter to plug into my Minidisc player and use my Airpods, but my wired headphones sound so much better than the Airpods that really wasn’t a viable option.  The other thing I could do was to get some small powered speakers that sounded good, fit my limited desk space, and didn’t break the bank. I looked, but nothing new really reached out and grabbed me. Then I remembered the AR Powered Partners I had back in 1999…

I liked them a lot, but—as I do so often with stuff—I foolishly sold them when I’d moved on to other interests and then later come to regret it.

Since they’re long out of production, I checked on eBay to see if any were being sold, and the vast majority of ones that were available (now over twenty-five years old) looked like they’d been ridden hard. So I set up a notification to be emailed whenever new offerings went up. A couple weeks ago a pair showed up with a Buy It Now price of only $70 (normally they go for twice that in awful condition). They looked mint—or at least as mint as any piece of used electronics can look after twenty five years. The seller mentioned that they were a single-owner and had been used gently indoors.

How could I not? They arrived a couple days ago.

For being so small (relatively) I’d forgotten how heavy they were. The enclosures are cast aluminum, and the 5-inch woofers have magnets almost as big as the drivers themselves. And yes, they were absolutely mint. They had scratchy volume controls, but a quick disassembly and a squirt of De-oxit into the pots cleared that up quick enough.

How do they sound? Fab-u-lous! As good as I remember. Now I’ve just got to watch that I don’t play them too loud!

From back when the name Nakamichi meant something…

We all need our escapes from the seemingly never ending existential dread that surrounds us these days, and Anubis knows I have mine. I’ve never escaped via illicit drugs or alcohol (no, really!), but as you’ve surmised if you’ve followed me here for any length of time, you know I do have my…obsessions.

Today I did a thing. I brought my 1984 Yamaha amplifier into the 21st century by swapping out the existing speaker binding posts with the newer style 5-way binding posts that accept so-called “banana plugs.” These also don’t balk at the thicker, 14-gauge wire I currently have running to my speakers.

It really wasn’t something I’d previously considered because the amount of work involved in swapping these posts out individually was well beyond what I ever wanted to do on my own. But one day I stumbled upon a link in an audio discussion forum to a guy who builds plug-n-play assemblies that simply replace the existing part. Done and done.

It took me the better part of an hour to swap out the part—mainly because I have the soldering skills of a 6-year old and the eyes of a 66-year old—but once I got everything put back together I was pleasantly surprised how easy it really was…and I was even more surprised that I did it without blowing anything up!

Does it make the amp sound any different? No, of course not. But I like the look and the future ease of using those banana plug connectors.
