I sold my 33 about 3 years ago. If I recall it needs either 120 vac or an
external *inverter supply* to supply the fils and High voltage from the
external inverter.

In the 120 vac mode it has a 120 volt cord & plug and an extra wire coming
out (of I believe an octal)
with an alligator clip. You ground the clip and plug it in the way which
has the neon bulb on the rear NOT GLOWING. I believe it must have had a
voltage doubler right off the AC line for the HV, but don't remember the
filament transformer. It would seem you could easily trace it out. I had
the service sheet. I'll try to figure out who I sold it to and get back to
you. It was a Prof @ the U of Chicago.

Try looking - asking he

Looks like you can get a manual here for $16:

I acquired a really nice Sideband Engineers SBE-33 transceiver and
would like to get it working. I already have several SBE-34's and
really enjoy these rigs. The problem is that I have been unable to
locate any documentation on the '33. Does anyone know if the power
plug wiring on the SBE-33 and '34 are the same? I know that with the
model 34 there are several jumpers and different wiring configruations
that must be made to accommodate 12 volt or 120 volt operation. Does
anyone know whether the two models are the same in terms of plug
wiring? Any help would be greatly appreciated.
