I am building a tube headphone amplifier. I built a AC/DC regulated power supply (220v AC to ~250v DC) but I am not sure about how good is the filter. The filter contains 120uF and 68UF capacitors, in between them there is a 0.4mH inductor. (170uF in total)
But it seems that most schematics use absurd filters - 10H inductors or really big capacitance caps. (1000uF)
Would my filter be good enough for high-end tube headphone amp or do I need to improve it with bigger capacitors?
What results would you get by using 'bad' filters? (More hum, more noise, short tube life..)
