Re: HexFreds in Tube amp?

Posted by Bernhard Fischer on July 1, 1999 at 22:52:16:
I have changed normal ss diodes in high voltage supplies and heater supplies against faster ones (hexfreds or schottky) and have heard the same sort of improvement as in ss gear - even in the heater supply!. So I definitely think it is worth the effort.
I dont know the circuit of the Quicksilver amp, but it seems to me that the rectifier bridge might be doing the rectifiing and the 5AR4 might work only as a delay for the high voltage. Some people did that because it was near impossible to get reliable 5AR4/GZ34 some years ago.
Best regards
