The black bar on the bottom of a 16x9 picture is narrower than the top bar when size and linearity are correct) and I have no clue how to adjust it. It's still got a bit of a wave as it did before, but I haven't changed any electrolytic capacitors yet. It's almost unbelievable how good the colour is now, it looks better than a lot of newer CRT televisions.

Also another question - an ideas what the blue knob just in front of the purity rings is for? (See pic)

Blue knob is blue lateral adjustment. CTC 38's had transistors in the IF stage go bad. They are 4 legged; ECG 161 was listed as replacement but were not a good choice if I remember correctly. The inverter transistors failed also. You will need #124754 and 124753 for OEM parts. I probably still have them. I hve never had to replace a nuvistor tube in a RCA tuner ever.
