Okay here's one for all you audio repair hackers out there. I inherited an old solid-state stereo receiver the other day which contains some dead audio preamp chips labeled SK9426. I can't find them in the IC Master so I assume they are somewhat rare/obsolete. Anybody ever heard of such a chip? Mucho thanks. -Charlie Thompson cs.utexas.edu!oakhill!radio!charlie

Anybody ever heard of such a chip? Mucho thanks. I rarely answer questions that start as illiterately as 'Okay' but.... The reason you didn't find the SK9426 in the IC master is that it's not an IC. It's a matched dual PNP transistor with common emitter leads, intended for use in differential-amplifier circuits. An NTE-43 is one substitute; check with your local tv repair parts shop to see if they have some. A note of caution: the SK series is/was RCA's "universal replacement" line of parts, just as the NTE parts are. Those parts were rarely used in new production (unless it's a homebrew) so you have to consider: 1) the unit you've got has probably been fried and worked on before 2) you're trying to find a substitute for a substitute, so there's no guarantee that the third-hand part is going to work at all well. Enjoy. - Brian

Try the RCA substitution book. I believe SK is RCA.
