Just get a big bag and test them?

Share This Page Tweet. Or is this caused by another part in the circuit? Those are about as close as you can get. And finally, 2SC or 2SC Log in or Sign up. As mentioned, the originals are TIP34B datasheetbut on the blown channel, someone has replaced the transistor with a 2SB datasheet. HyperionAug 4, I do intend to get the proper transistors soon, this was just a test. In stock at mouser. Thanks for the advice so far. You must log in or sign up to reply here.
I do not really understand how to find comparable devices, so I would really, really appreciate some guidance on this. The original output transistors were TIP34B, and I need replacements but they seem to be impossible to find.
OverLoadJul 29, No, create an account now.
This is very educational and fun for me. BinaryMikeJul 29, There are no adjustment points for DC offset in this amp. There are seven transistors in total on each power amp section.
I do intend to recap it, but I just don’t want to have any false hope over this getting fixed by that. You had a darasheet the whole time?! Thank you for the suggestions. I can find these, but 2sb868 do not know if they’re a good replacement. IMO the 2sb and 2sd would probably be the best sounding if you could get the original Toshiba parts – most are now made in China and vary in quality and reliability.
Maybe that is why it has been smoked? I guess I’m going to have to go with those, but I’ve gotten the impression that they are not entirely suitable.
Please identify the amp model, so this thread will be useful to future readers. Basically dataaheet sounds like you have a smorgasbord of output transistors. Do you already have an account? Tip 35C and 36C are higher powered versions and are still available. Can be found at most electronic distributors.

BinaryMikeAug 4, It arrived today, and now the amp works again. So I take it that these two transistors are the only thing that is relevant for the dc offset?
Without more info it’s hard to say what was original. Your name or email address: But I have no way of making sure they are matched. Is it likely that any of these could be causing a high dc-offset? I have an amp with a blown channel.
