Kenwood PNP or NPN bipolar transistors

[Aphix 10+ year member]

I've been trying to find a NPN or PNP bipolar transistor (I'm not sure which one it is), because I am fairly certain they are the cause of my blown kenwood not turning on or going into protect mode at all. When testing them with a multimeter in resistor test mode, they won't read back any voltage. I can't seem to find them anywhere online. The serial number printed on the two are FRH10A20 and FCH20A20, any help would be great.

If the amp doesnt turn on at all . You need to do somemore testing/trouble shooting before you start by parts. You need to remove them from the board to get correct readings on them Set your meter to diode check.
