Actually found it. There was a diagram on the inside of the back
This is one of my twin CTC-68s. Always had a green convergence problem on warmup, and no matter what I did, the colors always seemed off somehow.
Pulled the chassis, and replaced 5 capacitors.....3 on the convergence board and 2 on the main chassis. They look like hot dogs with grill marks....lol. Weird because ONLY this exact style of cap was affected.
Anyway, the set performs perfectly now, and the convergence is dead dead DEAD on (did I say dead on?

)......which ain't something that I'm used to seeing
