Those are rare beasts. Without a schematic or, as you say, an instruction manual, it would be impossible for any of us to help you. I have never even seen a pair of these amplifiers. Nor do I know whether they are Futterman type or Circlotron or other. Perhaps if you can supply some photos and a list of the tubes types that are used, one might start from there. Also, the amps were designed and/or marketed by Mr Park in Korea, who is also the maker of Allnic amplifiers. First of all, I recommend you consult with Mr Park via the Allnic website or via their dealer in Canada, David. He may or may not be able to help.
