TRIO / KENWOOD L-05M Monoblocks Repair Thread
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?
