What do people think of this classic preamp?
and how could it be improved?
I have put in a tube rectifier (5Z4) and a tube regulated supply so far on mine (VR150's and VR105's) and run the heaters from DC, it sounds good.
Although at full output i get 0.3v pk pk supply ripple in the form of my music is this acceptable?!
I dont know much about tube circuits yet but is there any advantages changes in topology can give like SRPP stages, active loads?
Anyway its a really easy preamp to build
Cheers
