This is a part of an off line discussion.? JR has a 465B with the trace off to the right.? From what I can tell, the CRT is ok, and most of the horizontal amp except for the differential stage is more or less (pot adjustable) in balance.
JR simulated the circuit with one simulator, I simulated the first stages with another.? His simulation doesn't seem to agree with reality (let alone the schematic voltages).? Mine (Multisim Blue, since discontinued) agrees with the schematic, but not reality as measured.? We're trying to get the first stage (differential, emitter coupled) to balance.? Having replaced most of the transistors, it's not happening, so he's doing the measuring, and I'm doing the "try to figure out what's going on" part.

Harvey,
Did you get s chance to compare my Simulator Voltages with your Simulator
Voltages yet?
