Ampeg Gemini 1 capacitor canister

Post by terryrocks »

Just received my replacement components from fliptops. However, the new capacitor canister is missing a tab. Can anyone recommend where I should route the lead?

What are the values in the old can?
What are the values in the new can?

I attached a schematic. Is this the correct amp?

It is the correct schematic:

Old:
Semicircle - 60microF @450v
Square - 40microF @450v
Triangle - 10 microF @450v
20microF @25v

New:
Semicircle: 70mIcroF at 450v
Square - 40 mirco @450v
Triangle - 40 micro @450

You will have to use a separate cap to replace the 20 uF @ 25V. No problem if it's over voltage say 50V, or nearly the same, as in 22 or 25 uF. Good idea to mount it somewhere it won't get toasted by the resistor it's bypassing or any other hot R's or tubes in there.

Seing as these Amps are now powered by more line voltage than there parts where spec for and all the internal voltages are higher I would up the voltage rating of the cathode bypass cap to 35 volts .
