Tonight I checked cathode current with V24/V25 out of circuit & saw no significant change. I disconnected the 68mmf caps previously mentioned and saw a noticeable boost in hv, maybe 1-2kv. Pulling the cap off the 6BK4 didn'[t change the HV. Next I'm going to sub another pot for the HV reg control. In-circuit it measured fine but I know that can lie. 2 things are pointing me in that direction: under some circumstances I can adjust the HV with it to a certain point but after roughly the halfway point there is no further increase. Then there was the fact that I was adjusting that pot when things went south. There are no signs of trouble from the pot by looking at it.
One thing i know-that horiz limiting coil is really putting off some heat! Anyway...excellent advice, miniman. Just the kind of stuff I'm looking for.
