Share This Page Tweet. So to sum it updo I go with ksc or ksc ? No noise or mysterious symptoms.
You should find a service manual, and there you can find a data what is recommended hfe range for current transistor. Yup, those 2sa’s have to go, little troublemakers that they are. But this doesn’t look like a transistor problem to me. Do you already have an account?

There are a couple of c Now I am working on one CA which has so much 2SC and in phono preamp I changed them by Toshiba 2SCBL because there it is very important get transistor which is ultra-low noise and high gain. I don’t have the service manual for CD 10 so I expect your proposals. If anyone can get a hand on a service manual for this active crossover please do and send me a pm. On some places I leaved those 2sc, just checked them by semiconductor tester are they good and cleaned legs, because they were blacksome of them I would replace by 2SC where the high gain and ultra-low noise is not important… So there are no advice change them all with xy transistor….
Well actually there is no trouble at all. On the transistors front they have used 2sc 32pcsand 2sa another 32pcs.

Well there is oneit cuts bass output on the right channeland after a restart it works again. Ok guysit think the time has come torecap and restore cd After 41 years the crossover performs flawlessly. Linear datashert low noise of course.
I would only exchange them cause of their age and perhaps the noise level. On cd 10 all of these ‘s and ‘s are line levelI don’t know if they need to datsaheet high gain. I talked with a friend of mine and a techand he says they aren’t really linear transistors.
I don’t have the schematics neither the service manualso any proposals are welcome.

Your name or email address: KaleJul 30, Ok these are easy to find I suppose ,and will try the nichicon way of course. What a rare piece of gear.
So the question here is what can I sub them with?
No, create an account now. The green bp of nichicon. HyperionJul 30, A pair of hotos. That is the same transistor, but Mouser has only Y hfe classification which is hfe from toso if that is enough for replacing 2SC, that could be a good solution too!
People I need a helping hand. Ok KaleI see what you mean.
