Yep, different versions over the years.

Still need the schematic if anybody has a link. I'll get it running
w/o schematic - I hope. but would be nice to have.

I'm sure it's the 'older version' It has a 12AQ5 for the first stage.
Second stage is 4 of them sweep toobs, and third stage is another 8
6LQ6 sweeps.

Yes, looks major homebrew. Three transformers with their secondaries
wired in parallel. They used solid green wire to wire the whole thing
up. One kludge after another, but I'm sure they did the trick as far
as making big signals.

HV relay was stuck. Will have to clean it up or find another.
The KA14DY-110dc relay looks like it might be a tad expensive to
replace. I'll check with the boss and see if he has anything to kludge
in

I just ripped out that hokey preamp. The guy who owns the thing said
all it did was amplify the static anyway.

Thanks for comments and links. Schematic while not being exact will be
of great help.

More later
