Re: Max Rectifier Capacitance
I agree with what RG and Bruce said, but I'm still very curious as to why you want to use a tube rectifier. If you want the sag of a tube rectifier, using 2 of them in parallel will defeat that because you will get half of the voltage drop accross them, and coupled with all the extra capacitance of the larger cap, you wont get much sag at all. The solid state rectifier would be cheaper and more reliable. I use tube rectos in all my amps, but I want that sag. Truthfully,my experience has been that on a typical 50 watt amp, I have found that using a 40 or 50uf cap for the first 2 filter caps with a tube rectifier is, as far as the ears can hear just as quiet as using 100uf caps with a solid state rectifier.
