I assume its a Hitachi, can’t find anything on the interweb on it. Waiting for it to come in the mail and may be a future topic here.
Lots of DC at the speaker outputs, started testing caps, almost all out of specs and many dead. After some assistance getting that fixed, my audio hobby was off and running!
It probably is a 2SC Went through the block diagram in the manual and figgered it had to be one of two transistors on the control board. When subbing transistors, you’ll make sure that the allowable Vce, IC and Pc are safely above in-circuit conditions, and certainly not lower then originally installed unless you can deduct what worst-case in-circuit current can be most often only a few mA runs while the transistor is ranked mA, so a 50mA ranked sub-transistor could do as well.
By no means an expert but this don’t look good So KSC should be good enough. So I know what I put in. Last but not least Like the Tek scope. Oh, and I would obviously replace the pair. NAD80, I got that scope about 3 years ago locally from craigslist. The pinout is different from the original to the SS but I could just put some insulators on the legs and make it fit? It’s capacity is also low 2.

But if the lower bandwidth would have been acceptable for the circuit, then the equipment manufacturer would have put it! Log in or Sign up.
Recapped the whole thing, sounds much better and a microvolt or two of DC at the speakers. NAD80Nov 24, How does RF play into this? So, what would be the best route to go?
Do you already have an account? I went to digikey and looked for a hFE TO and the only one that popped up was a SS, oddly enough had the code.
With all that, you can select the right sub Now, if you look at the newly SS transistorthen you’ll notice that it is an exact sub for the 2SC including EBC pin layoutand I would thus very much use that one. This circuit runs at very low collector voltage.

Didn’t work, had a bad cap and bad transistor. Notice the knee in the HFE curves below 2 volts.
The weak transistor has the legs blackened on it so it musta got hot but not hot enough to kill it? The digikey link for it is here https: I would certainly ensure to have a simular bandwidth. Did a couple comparison test graphs. For all other parameters, the KSC is better.
