By the time I get done sourcing and buying these tubes (everything I have is too old, I spent an hour rummaging through my loose tube boxes), I will have replaced every tube in the set, aside from the 3A3....including the picture tube.
This is the way these sets were when new? Holy hell, it's a wonder anyone that owned one ever bought another RCA!

When they got a few years on them most of them were like that.
Just like compactron sets ( GE, Admiral) you could replace most
of the low level tubes one at a time & see improvement step by step.
Problem was it got pricy & made the customer suspicious.
Actually had them come down & see on a few high tube count
jobs why.
After we pretty much stopped doing tube jobs the owner
took in a CTC36 charity case. He told me to use up all the tubes I
wanted for free since we would never sell them. Damn near
replaced all the tubes & it had one of the best pixs I have seen.
My only other major gripe with '36's & later hybrid RCA's was the rear
control assy,s were crap & they were awkward to do real work on.
We got the jig cables for them & just pulled the chassii to get
them right, saved time in the end.
