simple question

[lunastromoner]

Is the terminal strip on the jack side of the amp just for the FET input? I'm talking about the strip with one 20uf 500v sprague atom cap and a 2k2 resistor. Those caps are expensive, and I'd rather not get an extra one if I can help it.

Is there any change I should make when taking out the FET input? or can I just remove that part of the circuit?

Thanks a lot!

One more thing, what type of 100v .1uf cap is used on the manual PAB and OD switches and in the footswitch?

On most of the amps with that cap it's for the V1 stage. The ODS amps have 5 stages, Plates, screens, PI, OD stage and clean stage. So, yes, you need the cap. If you're not going to do the FET circuit most ad a 150k dropping resistor at the end of the string to pull down the voltage, simulating the effect of the FET on the rest of the circuit.

ok, thanks! I just looked at the schematic and that seems really obvious now.

do I use any kind of special cap on those PAB/OD switches? in the pictures they look green, and I haven't seen anything like that. does it matter?
