Re: 2465B vertical shift problem
Don't condemn the vertical hybrid just yet. First,toggle quoted messageShow quoted text
check that you have all of the proper power supply
voltages at U119 on the motherboard (see manual).
Next, check for a bad connection to the pins coming
out of the side of the CRT for the vertical deflection
plates, both at the output of the amplifier, and at
the termination circuit board.
Be warned that shorting either deflection pin to the
CRT's mumetal shield will instantly destroy the hybrid.
Avoid bending the pins close to the glass seal. They
are very thin pieces of wire.
I have the hybrids if you find you really need one.
When I move channels 1 or 2 down the screen the trace is compressed at the bottom. As if the gain near the bottom the screen is about half that at the top. The effect is identical on both channels. Channels 3 and 4 are OK. Channel 2 output is OK. This looks horribly like U400 is in trouble and I've heard these hybrids are unobtanium.
