The cabinet parts were reassembled and the chassis slid home and screwed down tight!

Wow. That set looks like it just came out of the box. The channel number plate is made of Tenite which always shrinks and warps to some extent. I had a Westinghouse wood radio with Tenite knobs that we’re slightly misshapen. It is unavoidable. Congratulations on such a fine and detailed restoration. I have bought two of those years ago but both arrived with the cabinets smashed. No one knows how to properly pack and ship something as heavy as a Bakelite TV.

I changed out the interlock cord and replaced the label.
On the interlock I used 2 small nylon spacers 1/4 diameter and 1/4 long. Then used 2 rivets and peened the end over. ![]() ![]() ![]()

I missed posting these photos of O'scope curves I took during alignment. The first one shows the initial response curve before I tweaked anything. Then the rest are self labeled.

Just to include a summary of what was changed during the restoration.
Capacitors: This chassis has about 72 caps. 21 paper caps that were all changed 6 electrolytic caps that were all changed There were 4 disc caps that I changed that were on the high side of tolerance. There were 6 mica caps that were changed. 2 were from the IF can on the tuner. 2 were 1Kv caps that were in tolerance but were changed because of the high voltage rating, the other 2 were in tolerance but changed anyway. For a total of 37 caps changed or 51%. Resistors: This chassis has about 72 resistors. All were changed. 54 resistors were out of tolerance. Some just barely all the way up to 278%. Of the 18 left, 6 were just a few points from being out of tolerance and were changed anyway. Of the 12 left, they were well within tolerance. 4 of them from the tuner that got changed while I was "in there" changing the 4 resistors that were out of tolerance. So looking at percentages: 75% out of tolerance 8% close to being out of tolerance 17% well within tolerance. Tubes: 18 tubes - 1 was shorted when I received the TV. 4 were on the low side of green. The 5Y3G rectifier tube was installed but should have been a 5U4G tube due to the transformer being one of the small percentage chassis that got a transformer from a vendor that didn't quite meet the specs for using a 5Y3G tube. The 7JP4 CRT displays a good picture, not a great one but a very good one though. |
