I have just been given a pair of these by Coliny from Derby, UK. One is faulty with DC on the output, the other is fine. As they are both in excellent condition for their age, I intend to repair them (if possible) and to document the repair. I have the circuit diagrams. The first thing is to obtain a source for the output transistors which are a 'special' type - 2SC2337 and 2SA1007. These are described as 'Emitter-Ballasted Transistors' (EBT's). Has anyone else any experience of these amps?
