There is a *ton* of good parts in that thing.
It won't make a good guitar amp, though, but - Hammond sourced
the vast majority of their speakers from Jensen, and the chances
are very good that you have something that has 11 vintage Jensens
in it. The 10" will be very low-powered, good for only Champs/Princetons
and whatnot unless used in multiples. They'll probably be rated
at 10 watts or less. The 12" may be high-powered Alnico types.
The amps may be used as is, but you'll have to put a preamp
in front of them - they're looking for the bodacious signal level
that comes from a Hammond console. Also, be advised that
those cabinets were designed to supply B+ to the earlier
organs, which had no HV supply on board. Consequently,
there will be a pin on the 5- or 6-contact input connector
which carries the amp's B+. *BE CAREFUL* when you're
messing around with that. You can get schemos for that
and most other Hammond stuff from theaterorgans . com -
