I would like to try a new relay driver transistor, but I can only find it at
Pioneer parts. It's only a @1.22, but they want almost $6 for S&H.

That is crazy. Anyway...

According to the Schematic, it contains two bias resistors.

I know I could check the transistor with my meter but that doesn't help in
the circuit (breakdown under load).
Plus I have the funcky bias resistors inside the transistor.

Do you know of a way to do a quick test on this without having a replacement
transistor?

Do know of a cross for this transistor: KRC101M ? A suitable cross would be
great.


It would seem Pioneer is as bad as Sony (or worse) at using hard to find
parts.

Here's the datasheet:

Yeah, those so-called "digital" transistors are IMO a joke.

If you have any general purpose NPN transistor like a 2N3904, you can
just add the two resistors and be done.
