Hi
Probably this discussion happened before, large capacitors were expensive and hum will decrease the higher the better ..... - yes probably true. But - does it make sense, as e.g. seen on many recreations of vintage studio equipment or classic guitar amp's to put up far more than ten times the values ?? To my experience - rather not. With DC - heaters (where large values make sense) and proper grounding design hum is usually not a big issue. You can easily overload tube rectifier designs even if the first cap is a suitable one. Tone of tube rectified guitar amp's (sag) to my experience changes with cap values and personally I like the values close to the original. The same with vintage studio gear - where these had maybe a simple tube rectifier and some 16 to 50uf or on larger ones tube stabilized and regulated circuits, we now see solid state regulated PSU's with 1000nds uF over the full B+ line. Any tonal or functional experience's on these more critical studio applications ? Given hum is under control - just vodoo to stick more to original values :?
