Hi,

has anyone got a schematic/layout for this one?

Is it identical to the the maxon pt-999 (reissue model)?

bluesbreaker62, thanks for the pics. That unit is in very good condition.

Is the DC jack an old style 3.5mm (1/8") type, or a modern type like the boss units?

3.5mm and it seeems it needs to be resoldered ;)
