Hello, I am new to audiokarma, this is my first message. I am looking for help, it is very difficult find info re H H Scot 345. I have bought one for restoration, nice looking, but in terrible condition underneaht. Missing resistors, capacitors, cuted wires ... it is a detective job. My most important question : in the schematic I have downloaded from internet is the center tap of the OT primary winding not connected!! Is it possible? How is PP working? I would very appreciate your answer. Koloman (in Switzerland)
