blew up the gemini

900 is higher than the schematic. I would suggest replacing it with a 470-500 ohm and then using 220-500 ohm screen resistors.
The copper cap is wired correctly. It is the filter for the bias supply. The bias voltage is negative with respect to ground, so the cap must reflect that polarity.
it is very common to think of the negative terminal of the electrolytic as ground, but there are many situations where the negative terminal is not connected to ground.

exactly what should it be? I only put 900 back in there because that's what I took out and it works but I'd rather have the correct piece in there.
I'd like to rebuild the vibrato section. it works but it's not snappy like it should be. I want to replace all the capsand I will either buy a new bug from flip top or make my own but I can't really read a schematic LOL.I have a list of every capacitor in there and I decoded every resistor in there. I just don't know which ones R4 The vibrato circuit
