Re: Any one been inside a Komet 19 yet?

I have the layout mapped out on paper. Tone control is Supro-style. Saturation control is the most unique element of the circuit. The rest is pretty standard 18 watt variation.

Re: Forming Caps correctly In Fenders

Preferably, you want the 100K resistor right after the rectifier or before the first filter cap. I generally just use alligator clips to stick the resistor in the circuit after desoldering the relevant wires. (danger: high voltages present. always discharge the caps before removing the resistor!). S...

Re: Forming Caps correctly In Fenders

Forming caps using the technique the original poster is using is definitely useful for amps which have not been used in 6 months or more. Will it restore filter capacitors in amps not used for 10 years to their original glory? Of course not. Is it necessary for new caps? Probably not but it won't hu...

Re: Forming Caps correctly In Fenders

Yes, lift the 220K balancing resistors or they will add to the leakage reading.

Re: rocket-ray

Creme Brûlée is a half powered take on the EF-86 channel of a Matchless DC-30. I have the prototype version of this amp. It's very voxy but with more tonal options.

Re: New Express build with Low voltage ???'s

First post on the forum but... shouldn't the pins 1 & 8 be tied together on the EL34 sockets? I know that the voltage drop across the 1 ohm resistor is less than 1 V but any voltage differential between those 2 pins may not be the best idea?
