Hi all - Happy Holidays
I've been looking around and I can't seem to find and definitive info regarding the values of filter and coupling capacitors in relation to where they are placed in the circuit.
Regarding filter caps - if you use a higher value capacitor at a later point in the B+ rail, are you wasting the added uf since a lower value was already used? For example, say you have 47uf > 30uf > 22uf > 30uf, is the last 30uf cap (that would be used for preamp stage) wasted? Should it just be 22uf or under or will using a higher cap make a difference?
For coupling caps - same type of question. Say you have, originating from V1 the signal path sees .01uf > .01uf > .047uf x2 (feeding signal to output tube grids) is it silly to use .047uf? Should you just stick with .01uf since it was the first value used or will .047uf affect tone? I know you cannot "add bass where it has already been taken away" but how strict is this rule aka when do you truly meet diminishing returns?
