Restoration Commences on 1947 RCA Victor 721TCS

[DavGoodlin]

I have four TVs using this chassis I haven't gotten to restore. a 721 I just picked up, two 8T241s and a 9T240.

This thread is encouraging because I dread replacing the dozen or more electro's these particular RCAs use.

Among my 21" sets, whatever Zenith used in '66 and 67' had reformed well.
BUT the two CTC-11's, 12's, 16x and 20c ALL needed the electrolytics replaced just to get rid of all the lingering issues caused.

I suspect the common ground fails and other things happen to these cans, creating high impedance connections internally due to corrosion from humidity, freezing and other factors.
