Info about filter

[überfuzz]

Does the cap size in the filter, rectifier, affect the tone of an amp. If yes how.

Anyone care to enlighten me, or pass me a good link on the subject!

Cheers!

Bigger reservoir caps are usually 'stiffer' sounding, while lower values of reservoir capacitors can lead to a kind of flabby bass and the sag phenomena. Higher value caps also lead to less ripple (although not really noticeable in push-pull stages), and ripple is usually sorted out by a choke filters in SE amps anyway, rather than resorting to huge capacitors. Rectifiers have a maximum capacitance, due to (I think?) the inrush current that's pulled on every cycle. In SS rectifiers this can reach 10's of amps quite easily, which I'm assuming wouldn't play nice with tube rectifiers past a certain capacitance. Personally I just stick the biggest capacitors I can in my builds, but then again, I'm not really into 'vintage' amps.

Thanks for the input!

In my country the juice was raised from approximately 220Vac to 230VAC some years ago. I think I'll go for the next size this time.
