Well changing the resistors from 1.5 to 1.0 would not do much.... I figured if they
were off, like the one you said was 1.5 and the other 1.6 and the pot .5 meg, then
it may have changed the range of HV if it shifted the bias on the grid of HV Reg.
So, with no plug on end of crt, hv changes by how much...?
And no HV lead attached to tube HV goes to how much...?
Can you make both of those readings again with no other work done in between...?
And one more.... HV connected, Plug on tube.... Brightness at cutoff - Dark Screen..... What id HV.....?
Make each of these tests with the HV adjusted to MAX.....
And write out each reading, and condition for the reading....
Acceptable answers are not "same as before" and or "they are good".
We need the condition, and the value - please.
And the cap between the grid and cathode of HV reg, you replaced that one....?
Anyone got an objection to running the set without that cap for a test...?
Just in case it's not working at that high voltage....
As a matter of fact, you should make these tests on both your sets with the same
chassis, or allow someone with the same set chassis to do them and have an
ongoing comparison..... And for each of these tests, please also record
the B+ Boost..... I think it's 390V.....
