I suspect that this has a really obvious answer, but my electrical knowledge is close to zero. Anyways:
I have a hammond organ and a separate Sharma (leslie type) speaker cabinet. When I connect the two and use the speakers in the Sharma, there's a constant hum. Not a buzzing or familiar amp noise, but a mid-pitched hum is the best way I can describe it.
I have the feeling that I've read an explanation for this before and that it has something to do with a mismatch between the power or....................shit I dunno.
Anyone know what I'm talking about?

Hammonds are a little tricky to ground. If you've still got an ungrounded plug, try turning it around. Old ungrounded equipment sort of fakes a ground by making a capacitor connection to one side of the AC, and of course it works a lot better if that side is the neutral side.

Capacitor? Is that French? I'm joking, but I really know very little about this.Scodiddly wrote:Hammonds are a little tricky to ground. If you've still got an ungrounded plug, try turning it around.

Can you really just turn them around? See, I'm in Ireland and our plugs are different, hmm.
The Hammond has it's own speakers and this only happens when I'm using the Sharma, but you think this is down to the Hammond's grounding itself?
