I own a 220V version of the PS Audio PPP power regenerator. One day, the unit stopped functioning properly with regard to distortion reduction and voltage regulation. After inspection, I found that the power transistors inside are damaged.Could you please provide the schematic diagram for maintenance purposes? I will only use it to repair my own device. Thank you very much.
Which country are you in?
Edited: I’m sure PSA technical will have no problem emailing you the schematics; that design being very old. However, I’d advise that you ONLY repair it if you can get it done cheaply. Else I cannot see it being worthwhile. Towards the end of it’s support, PSA only supplied complete refurbed regen boards as I recall.
Reach out to PSA tech directly - the email should be somewhere. I’m sure they’ll by happy to help.
Thank you for your advice. I have received the documents from PS AUDIO, which will greatly assist in repairing this unit.
