Hello everyone. I have a Krell KSP-7B preamplifier, but we lost the external power supply when we moved. I'm willing to do it. Does anyone have a schematic of the power supply and any idea what the supply voltages and currents are?
Thanks in advance.

I’m hoping for the same. Please let me know if you have any luck. I have one that’s been built but would like to improve it
The PSU for a Krell KSP-7B is +21 and -21 from all sources online.
Would anybody here be able to confirm that this board mated with an appropriate transformer and D9 cable work in theory?https://www.ebay.com/itm/225669036205

LDOVR.com makes very nice regulated stuff, so maybe contact him for +/-21V?

Aaah thank you! I guess that’s my next obvious adventure. To find what current is appropriateIt looks promising but doesn't state the output current. That pcb says "copyright 2015 Kevin Gilmore" so maybe you can find out more?
@Terry Demol I think you made the current PSU that is with my Krell.
Any chance you could PM me the specs? Sorry I’m new here and can’t PM direct
