Hi, I just recently breadboard the amp below and just wonder what would you consider as an acceptable minimum ripple at the B+ or the plate of 300B? The voltage values shown on 6SN7-300B are the actual value taken from the amp after a few adjustment with the ripple shown. I did not install the C2. Here are my questions1) what's recommended C1, C2 and C3 in this case? How do you calculate C2 and C3?
2) I am concern about the ripple as shown in the schematic. Should I increase the capacitance of the power supply caps to reduce the ripple? or there's a better way to do it?
3) What else would you recommend?Thanks in advance
