Re: Motorola SK-29M Restoration

Well, I've finished up the electronics, control panel and changer work on the Zenith X940 console, and since the weather is still too hot for doing cabinet work in the garage on it or this SK29, I've turned my attention to the SK29 's control panel. In the first page of this topic, I showed how I me...

Re: Zenith X940 restoration project, front panel rework

Thanks for the compliments, guys! I don't have the patience to do videos, but if there's interest, I would be happy to write up a more detailed description of that somewhat lengthy process in another thread.

Re: Zenith X940 restoration project, front panel refurbished

Finally finished reworking the front panel. Check out how it looked when I got it in the photo a few posts above. The foil with cutout, back lit letters is completely missing from the topmost portion, damaged/missing on middle and lower portions. Here's what it's supposed to look like: 1000003319.jp...

Re: Zenith X940 restoration project, the VM trip link

You are welcome, Bill. I couldn't find either of the above specific solutions in the literature or my Google searches, so I thought it was important to document for posterity! This trip link is just a piece of aluminum, easy to bend, so it seems like you should be able to correct most deformity issu...

Re: Zenith X940 restoration project, no full shutoff after last record

Well, plays records great, but I realized it was not shutting off after the last record , it "almost" would, the tonearm would return and set down, the control knob would only partially turn, but would not completely turn off. After observing things in action, manually running through the ...

Re: Zenith X940 restoration project, Microtouch end-of-play mistracking

FM stereo and amp still working, after many hours of play! New stylus and idler arrived yesterday, got those installed, and everything sounds great! But the changer has an end-of-play issue, stylus jumps a groove near the end of the record, like the trip link is binding, even at 3.8 grams tracking. ...

Well, the stereo light is working just fine this afternoon, so I'll move on to other issues for now, but I'm pessimistic that it's fixed, because I really didn't do anything! Maybe dirty transistor socket/leads that I cleaned a second time....

Re: Zenith Z940 restoration project

Well, turns out this is a Z940, for what it's worth. I think the models for the 940 started with X, then Y, then Z. This stereo mpx circuit is driving me crazy! Here's a portion of the schematic: CBCPaR02.jpeg TR13 is supposed to have the 19Kz pilot at about 35V P-P on it's collector, it was zero, b...

Re: Zenith X940 restoration project,, yellowed knobs fix

Anybody been successful in clearing the yellow in these plastic knobs? I've tried soaking in oxiclean, but no luck. 1000003295.jpeg In other news, I've been working on getting the FM stereo to work, good news is that the FM is really sensitive, back to back stations across the dial with only a short...

Re: Zenith X940 restoration project

Finished recapping the chassis this afternoon. Looks like the power supply cap cans had been replaced sometime ago, and one separate 1000uf/50v was replaced with 1500uf/75v connected with lamp cord (the blue one on the left).

Re: Zenith X940 restoration project

Chris, I agree completely! Unless I get lucky and find a parted-out panel, I'll work out something else that looks OK. When I began disassembling the changer, I found that the little flipper doohickey (the older service manual for the 1200 series that I have does not actually show that part) was ben...

Zenith X940 restoration project

Fixing it up for my daughter and son-in-law. I've got two projects going, this one and the Motorola SK29!

Re: Voice of Music - 1964 model unknown

Very nice! Looks like those control panels may even have etched lettering, much better, and more expensive, than just screened-on.

Re: WTB: Faceplate for Zenith X940 stereo console

Good suggestion, but the problem is, the lettering is actually cut into the foil so that the backlight illuminates them! I've never seen that done, it's a very precise cut for the letters. Here's a shredded piece that was in the record bucket. If I can't find a parted-out panel in a few months, whic...

Re: H H Scott Carlyle console, Zenith instead!

Thanks for all the inputs! I ended up buying a Zenith X940 console instead. He had several consoles, my daughter liked the Zenith styling better. This is what that model looks like, mine is a little darker, in walnut. It's still in the back of my VW Golf, in the garage! BTW, I traded my Magnavox por...

Thought I would wrap this up with my final work on this guy. I ended up replacing the Pfanstiehl cart with a Tetrad EVG 5632. Sounds MUCH better. 78's sound really good on it, too!

Re: H H Scott Carlyle console

So, got some more pix from the seller (the top view photo in my original post is not of this specific unit). It's SS, and schematics that I have found for the similar (but not identical) Scott stand-alone receiver, the 342, show that it uses several analog ICs, so I am wondering if that would be a m...
