Hello All,

I got this receiver from someone. It has the power amplifier with 2sk405/2sj115 MoSFET pair output stage and 2sk270 in the input differential stage. I would love to have service manual /schematics of this receiver. If you have one, can you please share with me?

Thanks,
Routhun

Transistor Replacement.

Hello, turns out one of the transistors is bad which is why a bunch of resistors went up in smoke. The model number for the mosfets in the amp don't seem to match anything on line. They are 2SK272 O type. Would anyone know which transistors would be a good replacement?
