RCA CTC-36 Woes

[bgadow]

I'd forgotten about that trait-I have a pile of CTC-53's but only one inside and cleaned up. It holds my record, by a quite a bit, for longest warmup. I think I timed it at over 60 seconds to get a raster. I do find the picture they make to a have a pleasant quality. Biggest problem with my "good one" is something heat sensitive in the vert circuit that causes a lot of drift until it's good and warmed up. I've replaced the tubes and caps, not sure if I started replacing resistors or not. That set hasn't been turned on in probably 3 years

Dont forget to check that diode. I dont know what make it is but to be safe you should heat sink it before removal (you maybe able to check in circuit, did not look too close to know for sure).

I will, definitely. I think to go further, I'll need a SAMS on the set. Going to have to order one online.

Happen to have any parts sets? I could use a brightness pot for mine....someone at some point installed a pot with a different shaft, probably replacing one that was defective.

I found resistors on the vertical board that changed value really bad.
My CTC51K wouldn't stop rolling and the size and linearity wouldn't adjust properly. Even when I replaced the 13GF7 and the 50MFD 'lytic.
My set is a real cheapie. It never came equipped with a degaussing coil.

As long as we're discussing this chassis, what the heck is this lever thing? Is this how horizontal centering is accomplished, or is it something else? I haven't touched it, but it seems like it would rotate in the opposite direction if it was....

prob loosen the yoke

It's a long screw for the yoke clamp. Actually for the whole yoke and convergence assembly.
