Yeah, I forgot about JB, don't have any on hand, but even our grocery store has some!

I hate to cover up the cool Motorola logo on the side of the can, so that's why I was considering the clear tape. Of course, no one will ever see it again, at least not for a long time! I used Elmer's glue to put the can back on, but I don't trust it to hold permanently. The Gorilla clear tape is on...

Yep, I cut that sucker off, put the cap negative lead through a hole, and tacked the positive lead to the stump of the post inside the can. I'll glue the can back on and wrap with clear Gorilla tape to stiffen it up. PXL_20260603_232745967.jpg When I first powered up the preamp, the right channel wa...

Preamp finished up. I didn't see any paper caps, unless those fat brown ones are disguised culprits. The two in the power amp, and the ones in the preamp are apparently working OK. I did test a few, they were OK. PXL_20260603_214647613.jpg The one electrolytic can (10 uF @ 400) was going to be a rea...

All tubes tested good, emissions in the mid to upper 90's on my Knight kit tube tester. All electolytics replaced, and one questionable disc, resistances all ok. Tube pins & sockets deoxed. Brought up on dim bulb tester, now working fine with my test speakers and music input from a Bluetooth ada...

Ordered a couple of Tetrad EV5632 half inch mount and adapter connectors yesterday (wanted an extra one on hand). Cleaning, checking and recapping the amp and preamp now. Interestingly, mine has 8uF cathode bypass caps on the two SE amp channels, but no fuse for the power transformer. Both schematic...

After much disassembly, I have determined that the 8T cart is beyond repair. PXL_20260527_215032940.jpg In summary, the two little posts sticking out of the damping gel are where the saddle (Yoke? Thingy?) attaches through those two little holes, the stylus shaft sits inside the Y part. Apparently t...

Have set aside the escutcheon label issue for now, working on cleaning the electronics and turntable so I can move those from my downstairs garage shop to my upstairs electronics shop. Wish I had the space to have everything on ground level! This console was probably stored in an attic for a long ti...

I've got some ideas of how to retain the original grill cloth--it's got a more interesting weave than the guitar amp stuff, and my wife thinks the "waves" are really cool! I'll be posting about that later... But for now, here's a problem I've encountered. The control escutcheon was dirty, ...

Uploaded Sam's SK-29M service manual, and also a single page schematic from 1960 Beitman's, to the Uploads Amps and Tuners section. Neither of those have a tuner schematic.

Yeah, it's PP for bass channel, SE for left and right.

PXL_20260515_222045525.jpg My first random fix on this guy is the torn off speaker enclosure door, simple enough, actually, since it's due to the glue failing on the hinge side of the enclosure. While I was at it, I found that the inverted magnet oval midrange was completely white with what may be ...

Picked this classic up yesterday, nice young lady seller on FBM with honest photos. https://www.facebook.com/share/1HrkX2MqD8/ It's phono - only, cabinet in bad shape, but I have plans for that! Here's a couple of screenshots from the listing, first the beauty shot, then the ugly one. The left speak...

Wow, what an ordeal! Your client probably doesn't realize the bargain she is getting with such expert work!

Sound wise, I think it suffers greatly from the side firing speaker arrangement. Sounds pretty dull when listening to a record from a position in the front since all the treble is shot out sideways. I'm also wondering if the replacement cartridge has different enough characteristics compared to the ...

I've bought several types of Bluetooth adapters from Amazon over the years, but the one I installed on this project works really well. It has a "3D" button which sounds like it boosts bass and treble, and that makes it sound really good on this unit. After some experimenting, I ran the Blu...

It's been a while since I posted my progress on this guy, but I've pretty much finished up so here's the latest. The oscillation issue kept raising its ugly head:-I realized that there was still a low-level 8-10 Hz background oscillation that was present almost all the time, could only see it on the...

Great piece, thanks for sharing! Serling comes across as a thoughtful and intelligent guy.

FYI, the schematic I uploaded (from radiomuseum), and the one in the 1964 Beitman's book are only for the amp, which worked for me since my model doesn't have the tuner. And the component designations in the radiomuseum schematic don't agree with the PCB markings in my model, though it's accurate ot...

Great story, thanks for sharing!
