What would be very interesting is to see current draw with and without the RF and IF tubes installed. If it's the caps you'd still be seeing significant current being drawing without the tubes in. Time consuming work but very rewarding if you can narrow down the point of failure.

well I just ordered 21 of these,

they SAY the the ones in there are ceramic, but I am not sure what the hell they are, I tend to think they are more like the elmenco tubular ceramic shell caps bombs that were in my CTC-16LX, they went bad as well, i took one apart and it had wax seals on the ends, and to quote Electronic M, It is usually best to assume in any tube TV that any cap 1000pF (=.001uF) and up is paper unless it is flat disc ceramic or a later film type such as a Sprague orange drop.
I just should have replaced them all at first :/
