Looking for a 450V to 500V adjustable power supply for tubes
2017年11月11日 · I think one way is to stack my 0-60V bench supply with the 0-400V supply. Float the 0-400V supply up on top of 60V adjustable supply I already have, to get 460V maximum. That should be enough for all the tube projects. I will have up to 1A of current capability. I can use this all the way to the wood board prototype amp.
