Gandert,
The +30 volts comes from the 760 power supply chassis. Without the 760
power supply you may have to make up a power supply for the
crossover/preamp, a small transformer with 15 to 20 volts AC output a
rectifier and a reservoir capacitor of a few 100 uF would probably do, you
don't need a lot of power just make sure that it's sufficiently smoothed.
The stock 760 amps had quite a good sound, I think that Leslies designed
them to sound good with an organ, rather than to be Hi-Fi. The Dynaco would
give you more power than the stock amp. in your L-100 (one pair EL84). I
don't know how easy it would be to adapt to your purposes though.

the 760 amp, but I woulds like to have a valve tone. And I see all these
comments on the zone about replacing the 760 amp for a tube amp. I do know
off course that not any tube amp will sound better, but any recommends? On
the dutch ebay i saw a Dynaco with a stereo tube amp. It uses el84 tubes
17,5 watts per side. Could this be any good?
