No, create an account now. There are a couple of c I don’t have the service manual for CD 10 so I expect your proposals.

On cd 10 all of these ‘s and ‘s are line levelI don’t know datasjeet they need to have high gain. If anyone can get a hand on a service manual for this active crossover please do and send datashert a pm. Linear and low noise of course. 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!

Well actually there is no trouble at 2sf1815gr. Ok datashet are easy to find I suppose ,and will try the nichicon way of course. So to sum it updo I go with ksc or ksc ?

KaleJul 31, I don’t have the schematics neither the service manualso any proposals are welcome. Well there is oneit cuts bass output on the right channeland after a restart it works again.

Yup, those 2sa’s have to go, little troublemakers that they are. Yes, my password is: Ok KaleI see what you mean.

So the question here is what dwtasheet I sub them with? 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.

No noise or mysterious symptoms. It is not a simple answer. People I need a helping hand. Hyperion datashdet, Jul 30, Ok guysit think the time has come torecap and restore cd After 41 years the crossover performs flawlessly. Share This Page Tweet.


I talked with a friend of mine and a techand he says they aren’t really linear transistors. I would only exchange them cause of their age and perhaps the noise level. KaleJul 30, dattasheet Do you already have an account?

Along with the electrolytics. A pair of hotos.

In the raw among the others. 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….

But this doesn’t look like a transistor problem to me.
