To clarify, what I mean by oscillation is, some weird harmonics in the 95v line, that tend to show with RF input as unstable picture and sync, it can be fine for some time and then just go nuts, and I can get it to stop by briefly shutting off the RF modulator and turning it back on.
As mentioned before, the source for 95v is a bit odd in this set, v8 & v15 with one filter c2b.

C2 b 40uf the only filter on the 95v line, is on the front of chassis, focus socket is at the back, (95v is being used,)
v8 1/2 the source of 95v is on the left side, v15 the other half is on the right.
I'm hoping that adding another filter cap at the focus socket may help things run more stable.
For the most part, when tuned in and NOT oscillating, it has a pretty good picture for it's age.
