output transistors and tested them with a DVM. Not sure which is the Base or the Emitter but on the diode check I get approximately 425 on one pole and 1.0 on the other. I tested all of the output transistors and they all are around the same reading 425-440....

chip in at least some of > the locations. It's certainly among the best bifet chips that you can get > these days now that the Motorola stuff is all discontinued. Be careful about loading, though; the TL07x has an insipid output stage, and it hates driving...

Pioneer amp SA-930 no output, what causes?. Archived from groups: rec.audio.tech () Thanks for the idea of a blown fuse. Not the cause. there's one fuse inside the unit. it looks good. the unit lights up and gets hot. just no output. elsewhere online...

determined by only *one* output. You don't have to take the output differentially. Note, that the intention is op-amp buffers be used at the collectors as output drivers. There is no intent that any final outputs should be taken directly from the...

two transistors were suspect. One I can find and fix. The other transistor is part of two pairs of transistors on the amplifier block. Apparently these two pairs of transistors come in matched pairs. One is a 2SC960/LA43 the other one is a 2SA607/LA43E....

pair" I'd want to bias? By pair I mean two electros replacing an original single cap, with the + sides tied back-to-back and the bias injected there. Would the output stages of such regulators impact the signal fidelity? Thanks again for the help and...

Smoke out of the transistors. The "offset" pots, if present, are used to balance out small errors or inequalities in the circuit's symmetry, thus ensuring that the average voltage coming out of the output transistors (the "DC offset") is close to zero....
