I need output transistors model numbers for a Luxman 5M21
I am repairing a Luxman 5M21 on which the output transistors have been replaced by MJ15024/MJ15025. The amp has much higher distortion figures than it should have. I am trying to get back to the original output transistor models but I don't know what was originally used by Luxman.
I would appreciate any information on this. If someone out there has a Luxman 5M21, it is very easy to read the model number of the output transistors just by looking through the top grill. Thanks. Joe.
