Hi!

Does someone know what are the two diode-like parts soldered on the socket of the 5Y3GT rectifier? They are not shown in the schematics for the 5E1 or 5F1 model this amp is supposed to be a reissue.

Thanks...

Fast soft-recovery controlled avalanche rectifiers. The 5Y3GT rectifier tube is getting a little help.

Very interesting, RJ. These are FREDs right? Are they placed before or after the tube? ART

They are coming off the transformer before the tube. Same as the Deluxe probably.
