Yeah - I took the knobs and face plate off and stashed them out of harms way. This one should be pretty easy. The amp boards and tone/amp board just unplug!
I grew up in the 60's and 70's, so I remember drooling over some of this gear on the shelves at some different retail outlets. I started collecting some a few years ago and have picked up some nice gear. My favorite is a Pioneer SX950 in minty condition. I got it for $150. The pots all need deoxit'ed, but otherwise she's a real beauty. I have a couple of Marantz receivers I love, A JVC, and a Sony STR-6800. A few others too, but these are my favorites.
I'm right there with you on the SX-x50 series. They might not be audiophile grade, but I still remember the entire line on display at Team Electronics. The golden glow left a lasting impact.
The SX-950 is the only one in that series I still need to find. I can only hope to find one for under $500 that isn't seriously abused.
All buttoned up and ready to be picked up. Every e-cap and a handful of small signal transistors were replaced. The power supply and output transistors got new thermal compound. The speaker protect relay was in good shape, so parts were only $75.
Listening to this combo today. It seems to have a few issues when you first turn it on for about the first three minutes. It only has one channel after that both channels start working and it works great all day.
A couple of years ago, I opted to go the simplicity route (lots of reasons). Bought an Arcam SA20. Love it.
Sold my 1973 Accuphase P300 to a friend. I had fully recapped and sorted myself with new switches and pots. What a beast it was. Of course, I regret selling.
I read through that one Tom.
I don’t believe I will bid on these when they come up for auction as I don’t think they will go for my price range. Lots of people go crazy over this old RF stuff.
If you have everything plugged into the same outlet or strip, my money would be on a dead cap in the power supply. That preamp has 3 regulated supplies, so there are lots little caps in those circuits.
These I’ve had since the early 90’s. I’ll have to find someone that can fix that for me.> @Tom_S said:

Hit a dirt mall in Cincinnati....
Those speakers (with the recessed tops) could be fitted with black / smoked glass tops - aka the old JBL L300s. Read where they were good for illicit white power back in the day. But still good looking.
I know I've seen a pair of Zenith Allegro in my past somewhere, and they had the same grill frames just as those do. Not sure where I saw them though...
Sad those old Bozaks were priced to sit there for eternity. Actually a lot of cool stuff/furniture was, it's kinda disheartening to go to these places anymore. Only things I came home with were a couple records, Larry Carltons self titled album and Lee Ritenours "Rit" album...$8 a piece.
The owner of the Marantz picked it up yesterday and left me with his latest score, an HK 330B. The tuner wasn't working at all, but he didn't want to put a lot of $ into it. Turned out to be an easy fix.
Not really sure. Might have been the pass transistor. It measures good, but that's not at working voltages, so it's suspect. It was under a buck to replace it while I was in there. I ran this for 30 minutes last night and nothing is getting hot, so I hope that fixed it. It's nice sounding little unit - with somewhat tube like warm sound.
The guy who sometimes brings me gear to repair knew I still needed an SX-950 to complete my SX-x50 receiver collection. He spotted one on Marketplace in North central Iowa. It was a little more than I wanted to spend, but he kept an eye on it. He picked it up yesterday when the price dropped and offered to let me have it for the purchase price + some troubleshooting on the NAD below it. I'll take that deal all day long! We've developed a good friendship over the past year or so and I'm very grateful for his thoughtfulness.

That's a ton easier than some of the rats nest connected old gear.

Here is the rest of the Nakamichi system.

beautiful
Nice piece!
Great work Tom!
Tom , what are the chances you have one of those round push buttons for a Marantz ?
I have a few varied Pioneer knobs and that's about it. Sorry Nick!
NP , actually I think I may have already asked you that awhile back

NICE! I found a thread on Audiokarama and they made 2 versions of that amp. He changed out some of the smaller caps and had it working again.

Wish this pre-amp didn’t have a ground loop in it. Small audible buzz with no volume.

Wish every manufacturer would have done this!
Onkyo A-7040 integrated amp - restoring to flip.
That is a welcome sight.

But what caused the cooked resistors?
