I will try replacing that one on the AGC control, then check ESR on all the 'lytics in-circuit to be thorough.

I understand that multi-section lytics can present odd issues such as high impedance in the common ground, resulting in coupling of ripple between stages. My CTC11 worked OK on its originals until 2008, when it got the bends and I shut it down.
My other CTC11 had all its caps replaced, seldom used but works reliably.

To bridge all the 'lytics while observing pic, I used a 40mf @ 450v but that did not accomplish much. The alternative is to replace all 3 cans' caps*, which needs done regardless.

*I was thinking I could skip that step to see what set gets the "full monty" first!
