Re: Fender amp copy
"Not for the 6L6GC specified in the design as these are rated at a plate dissipation of 30W so a pair in class AB push pull is well within the rated power." AFAIK you don't double power OP, EG it's not 2 x 30w as only one valve is working in the class B part of cls AB PP at a time, therefore two 6L6's biased at 30w each will give you 30w OP.
Re tremelo circuits I'm working on a WEM amp, see attached schematic. The amp has separate mic IP's which give a clean hum free OP, but using the tremelo IP's results in quite bad hum, this is refardless of the tremelo being on/off. I've been over the wiring/layout and checked components but am convinced the hum is down to the design. What's your circuit like as regards noise? Are tremelo circuits noisey on the whole?
Andy.
