Default 6v & 90v DC Power supply

Hello Spehro,

In case of a Hammond organ it might since it has a speaker. Of course,
it's a tube amp but that is a whole other matter which alone could make
this thread balloon.


Don't some of them have rotating speakers?


That was an accessory item, a Leslie speaker. A huge cabinet with a
rotating speaker on slide contacts, motors, gears. We don't have one and
we wouldn't know where to put it anyway. The amp under the organ is only
20W AFAIK with a huge speaker. That's real watts, not PMPS or whatever
kids call "power" these days. Meaning it can make the sound of a large
pipe organ and not lose steam after holding the bass chord for more than
a hundred milliseconds.


Sure, but can you flip a switch and be playing the flute or er-hu?


Actually you could. Ours doesn't have the flute presets but drawbars.
With these you can set the ratio of all the harmonics and the manual
shows the settings for a lot of common instruments. Some sound real,
some don't. But we also have a small environmentally friendly (zero
electric power, made from wood) flute. Not that I can play it but my
wife can.

Regards, Joerg
