My next restoration victim, Silvertone

[Doug66]

Eric, have one of those and have given up on it. I never could get the horizontal to stabilize. I rebuilt all the couplings and changed the horizontal frequency coil and finally set it I the shed. Maybe I will try again sometime.
I assume yours has those large copulate with about 13 parts per unit.
Keep us informed. I will follow this thread closely.

Your's is a later model, that uses PC boards.

When you go to recap that beast, don't make the same mistake I did back in the day. On the first one I got ahold of, that double-ended electrolytic needed replacing. The replacement had a red wire and a black wire coming out each end.
I (mistakenly) assumed "aha, each red wire goes with the black wire at the other end", and proceeded to wire it accordingly.
The set actually came on, but with gawdawful hum bars. Then after correcting the goof it worked fine and nothing got smoked.

I tested all the tubes, only one was bad.

The 4BQ7 in the tuner showed a short, there's a note from a tech on inside of the cabinet that says "4BS8=4BQ7" and sure enough, the tube chart shows a 4BS8 in that location.
I found a NOS 4BS8 to replace it but it too shows a slight short on my tester, possibly my tester is just wrong on this one, in any case I'm going to use the 4BS8 since that's what it originally came with.

I also gave the chassis a bath, it was filthy and some of the plated parts had that green Cadmium corrosion on them, I used some spray cleaner and a wire brush on the corroded parts, followed by a hot water bath, I avoided getting the flyback soaking wet. After that it went in the oven on the lowest setting of 170 for 15 minutes and then left it in another 30 minutes with the oven off, it came out sparkling clean!

I found this model in the 1956 Sears Wishbook catalog on http://www.wishbookweb.com/

Turns out the cabinet is Aluminum so what I thought was rust inside must just be 60 years of dirt and whatnot.

The tube shields are unusual on this set, I couldn't figure out how to remove them at first. They are two piece thin spring steel attached to the chassis, each half wraps two thirds of the way around the tube making a nice tight fit all around, you simply have to pull them apart and they open up exposing the tube, a really ingenious idea since it makes a good connection to the chassis and it holds the tube firmly in place.

Oh, and I found the Damper tube, hiding at the very bottom under the sweep tube, it's the usual 12AX4, you can just see the socket peeking out bottom right.

The tube shields were a U/L requirement, where they couldn't be removed and left laying inside the cabinet to contact the chassis and energize the metal cabinet.
BTW, the middle set, shown in the wish book, the one with the knobs and the dopey handle on the side is shown in the movie, "Godfather I".
