About 20 years ago when the Mystery One came out I really wanted one, but it was out of my league. I've gotten over that but I'd like to see a schematic, not to build but just out of curiosity.
Does anyone have one? I've searched to no avail.
Cheers, Steve

Hi Steve
With this email, hope to find you doing well, my name is Niwat I live in Thailand, by luck just about 8 years ago I managed to purchased a pre-own Unison Mystery one from a pawn shop a good looking preamplifier best paired up with my old buddy Smart 845.
Just last few day ago my Mystery One get sick no more singing, hopeless to find competent tubes gear repair shop down here so I am searching for schematic to repair myself.
Kindly let me know if you have the mystery one schematic in your hand.
Kind Regards
NiwatC.

Sorry, never got a copy of the schematic. As I understand it bias voltage is supplied by batteries. Have you checked these? Check the rectifier tube as well. The circuit board doesn't look too complex so you might be able to generate your own schematic.
Best of luck, Steve
