How do you get matched pairs of transistors normally? They spec’d 2SB and comp 2SD as suitable as well. A random pair of KSA devices from the same batch are probably matched well enough for the input diff-amp stage, especially if you get them from the highest hFE ranks F or E.
RuxmanJul 29, In stock at mouser. I’ve looked at the datasheer several times before but did not find anything that I could understand that well. Or is this caused by another part in the circuit?
HyperionAug 4, Dr TinearJul 29, Discussion in ‘ Solid State ‘ started by RuxmanJul 29, Some are probably very. I see that 10R series base resistors are used xatasheet the output 2eb688, so faster output transistors are unlikely to cause difficulty.
Back to original question. I do intend to recap it, but I just don’t want to have any false hope over this getting fixed by that. I have taken out the TIP on the blown channel and everything is shorted. I can find these, but I do not know if they’re a good replacement.
It arrived today, and now the amp works again.

Tip 35C and 36C are higher powered versions and are still available. Please identify the amp model, so this thread will be useful to future readers. Oregon, land of magnificent stumps. I guess I’m going to have to go with those, but I’ve gotten the impression that they are not entirely suitable.
Need a modern replacement of a TIP34B transistor
Basically it sounds like you have a smorgasbord of output transistors. FootFungusAug 4, 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.
I do not really understand how to find comparable devices, so I would really, really appreciate some guidance on this. Maybe that is why it has been smoked? No, create an account now.
