Vintage Synth Repair

I have a Hammond C-2 comming through a Leslie and lately its been 
making a noise that I can only describe by compairing it to the noise 
made by one clearing their throat. Something else that may be 
significant, the organ needs to be played for at least five minutes, 
before the noise occures. Also, I can volume down and noise will 
subside. I have sprayed the reastat, with no positive results. If 
someone has succussfully dealt with this or a similar problem, I will 
very much appreciate any tip that might help........ Thank you very 
much, Mark, from Missouri.............

Hello:Most of the time this type of noise appears it is caused by a bad 
connection or a bad Mercotac  in the leslie,if you shut off or disconnect 
the leslie motors and the rotor is stationary and the noise does not occur 
then I would assume it is the Mercotac,that is assuming your type of leslie 
uses one.

Which Leslie do you have? If it is a tube type most likely it is the
rectifer tube which is a OC3 in a 147. I had the same trouble with one
of my 142s and it was the OC3 tube. Hope this helps.

That's *NOT* a rectifier tube,  it's a voltage regulator...

What Leslie are we talking about here,  a 122 or something?
