Ok, resoldered the PCL84 socket, changed the three EF80 in the image/visual IF stage. Also changed the grid resistors, as they looked a bit baked. But they were all within specification.
DC measurements on PCL84: g1 = 147 V, g2 = approx 4V, ap (anode voltage) is about equal to g1 voltage. Actually it starts out a bit higher as the set warms up.
Any hints on this at all?
g2 should be 15.5V according to the schematic (I have contrast maxed out), but then again the oscillogram only shows a 10Vpp signal with signal applied, so it may be right (?).
Hopefully I haven't ruined the CRT at this stage
