    Yamaha CR-2020 TR707 / TR708 mounting

    Are the TR707 and TR708 emitter pin correctly depicted on the Yamaha CR-2020 relay board diagram? That is to say, does the black pin on TR707 and TR708 correctly identify the placement of the transistor emitter? Leaning on Oilmaster's wonderful diagram description on his post, the rightmost...

    Hello, I recently got my hands on a Pioneer SA-9900 amplifier. I'm not exactly sure what's wrong with it but so far I have determined that one channel has zero output, no hum while the other channel sounds clean but not as loud as it should. I've hooked it up as following: Pioneer TX-9500...

So I bought a pair of 2SC1116A, possibly fake ones, off "e-pay" and 3 x 2SC1116 originals from a tech who pulled them from a...
