CTC-5 21AXP22 convergence

[Penthode]

The Super and Deluxe share the same tuner, video IF and luminance amplifier. If the agc is cranked to maximum and overload is not reached and you confirm a good level RF input, gain must be lost somewhere.

My CTC5 had low gain which simply was a bad 3rd VIF tube.

Even though my set had a quiet previous life, I found the video IF alignment off. A touch up further increased gain.

I now find the agc control set about mid-point. Cranking it up further sends it to overload.
