After a long time of sitting about this TV is finally getting its turn at restoration. I pulled the chassis and found that it had been partially recapped and some of the repairs looked quite old. Much of the earlier repairs are sloppy and it looks as though the shop used whatever parts were on hand There are still a lot of paper caps and old electrolytics that need to be changed. Many of the paper caps have been replaced with ceramic discs. Most of the tubes are replacements. I suspect the CRT has been replaced at some point but it checked good on my tester when I tried it again this morning. The chassis needs a really good cleaning but first I wanted to get the power supply working so I could test the set and find out if the major components were good.

The selenium rectifiers each had a silicon diode bridged across them, definitely not good workmanship. I replaced the rectifiers, two electrolytics, the caps across the AC line and the cord. I also installed a fuse holder so I can have some protection for the transformer from shorted caps.

I put the chassis in the cabinet and tried the set out. With the plate cap off of the horizontal output tube I got sound and tuned in my in-house analog station on channel five. I reconnected the HO tube and got a bright full raster and a decent picture. The tuner is seriously dirty but it looks quite good.

The first program I tuned in was I Love Lucy, seems appropriate for a 1952 TV. I wish the tube had a little more brightness but it is non aluminized so I suppose I shouldn't expect modern set brightness levels. Yes, the ion trap is adjusted correctly. Linearity and synch are good, tone is really warm from the large speaker. I think I have a really good one here. I just have to correct a lot of sloppy repairs and finish the recap.
