Subject: SB-401 problems

I've been soldiering away on bringing back to life the SB-401 I picked up for
next to nothing at Shelby.  A good cleaning, spraying, etc. has brought most of
the systems back up, but still no play.

The biggest puzzlement is that I'm missing some 200/250 range voltages.  I've
tracked the circuit back to the power supply and it seems to be cranking them
out.

At the moment, I have good high voltage and alc on the meter but low plate
voltage.  No grid drive at the moment.  The missing voltages are on the
compactrons.

Any suggestions for this lost soul?

I'll tackle the 301 next.

Thanks
