Subject: [hammondzone] Leslie 330 - theoretical question

So I had a Leslie 330 that came up dead, a couple years back: no sound, motors not running, nothing.? --But, no blown fuses.

I finally had a chance to get into it tonight.? T2 was getting very warm to the touch, very quickly.? So I investigated around that part of the circuit... the culprit turned out to be C1 (250uF, 35VDC).? I replaced it and everything's fine again, running on a combo preamp pedal.

(Incidentally that's the second time I've had a D.O.A. condition on an 11-pin Leslie, due to a faulty C1.)

The thing is, when the fault first appeared two years ago I had been trying the Leslie out on an otherwise untested, new-to-me B3000 (using the built-in 11-pin output).? Unfortunately, the 330 had sat idle for awhile at that point; and I didn't have the sense to test it in a "known good" configuration before I plugged it in to the B3000.? As a result, when the Leslie turned out not to work, I didn't know whether maybe there was a problem with the B3000, or the Leslie had just happened to fail at that point.

So my question: assuming everything on the organ is stock, is there any way the B3000 connection could have caused C1 to give up the ghost?? Or was that fault most likely a coincidence?

Am I asking for trouble if I try the Leslie on the B3000 again?

Thanks in advance for any guidance.
