Fixing a Yamaha M-65 For A Friend

[takada]

Are they original or not?

Those look to be original.

Which are factory transistors, Toshiba or Sanken? In my amp soldering looks like a factory work (I think so). But one my friend have also M65 and he said that the transistors are Toshiba in his amp. I want to know, was my amp repaired or not...(transistors)

 

[OMGCat!]

I've had three M60s through here that had Sanken output transistors and Toshiba drivers.
The PNs also match the service manual so both are likely original.

As the CAT said. Those are OEM transistors.
