Dear Group Members!

?

Today I have to ask for your help. All of a sudden we experienced a crackling noise in our C3. It?s not constant but comes up every few minutes. ? It sounds like the noise a bad tube makes.? So I exchanged all the tubes except the rectifier that I did not have. Still crackling. ?The noise is faded when the volume pedal is faded.? It is not in the leslie 147 and not in the (solid state combo) preamp.? Now it must be something in the C3?s preamp.

I could?imagine it?s a capacitor in the signal path. I?m not into electronics, but I?can change single components and did that before on tube amps.? This time I?m really worried as we use the C3 constantly in the studio and it makes us sick when the organ is ill......

So if anybody has experienced something similar and might give us a hint - that would be great.??I have a schematic?of the circuit.?

Thank you,
