Yes, my password is: No, create an account now. So the question here is what can I sub them with?


Do you already have an account? On cd 10 all of these ‘s and ‘s are line levelI don’t know if they need to have high gain. You must log in or sign up to reply here. Yup, those 2sa’s have to go, little troublemakers that they are. Along with the electrolytics. 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 all.

2SC1815GR Datasheet

KaleJul datasheer, You should find a service manual, and there you can find a data what is recommended hfe range for current transistor. Ok guysit think the time has come torecap and restore cd No noise or mysterious symptoms.

Share This Page Tweet. KaleJul 31, What a rare datashset of gear. I don’t have the service manual for CD 10 so I expect your proposals.

Datasheet download …

HyperionJul 30, The green bp of xatasheet. People I need a helping hand. 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….

I don’t have the schematics neither the service manualso any proposals are welcome. Your name or email address: Overundr1Jul 30, There are a couple of c Ok these are easy to find I suppose ,and will try the nichicon way of course. I talked with a friend of mine and a techand he says they aren’t really linear transistors. After 41 years the crossover performs flawlessly.


Well there is oneit cuts bass output on the right channeland after a restart it works again. But this doesn’t look like a transistor problem to me.

A pair of hotos. So to sum it updo I go with ksc or ksc ?

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. Log in or Sign up. It is not a simple answer.

Ok KaleI see what you mean. I would only exchange them cause of their age and perhaps the noise level. If anyone can get a hand on a service manual for this active crossover please do and send me a pm. In the raw among the others. Linear and low noise of course. On the transistors front they have used 2sc 32pcsand 2sa 2sc1815ge 32pcs.
