Can be found at most electronic distributors.
A total power supply voltage of 88V is really asking too much adtasheet anything in the family, even if the devices were pre-tested above that voltage with a curve tracer.
No, create an account now. I do intend to get the proper transistors soon, this was just a test.
Do you already have an account? Yes, my datazheet is: HyperionAug 4, It’s an OEM amp Dynaco used TIP transistors in several of their designs. Also, a small 1uF cap had exploded on this channel.
Back to original question. Without more info it’s hard to say what was original. Some are probably very.

Thank you for the suggestions. If anybody is interested, here’s a schematic of the amp GIF, kB. TIP33 and 34 are still available – should use the “C” version v.
I ordered a new TIP transistor before starting this thread. Log in or Sign up.
No matter where I put the probes, I get continuity. OverLoadJul 29, I see that 10R series base resistors are used in the output stages, so faster output transistors are unlikely to cause difficulty. I can find these, but I do not know if they’re a good replacement. But I have no way of making sure they are matched. BinaryMikeAug 1, A random pair of KSA devices from the same batch are probably matched well enough for the input diff-amp stage, adtasheet if you get them from the highest hFE ranks F or E.
BinaryMikeAug 4, Any help would be really appreciated! This is very educational and fun for me.

Your name or email address: I have an amp with a blown channel. I guess I’m going to have to go with those, but I’ve gotten the impression that they are not entirely suitable. Thanks a lot for the help! Man, it is difficult to find these output transistors.
The 2sb has a higher voltage rating, and the is rated at higher current. The two outputs, and then very near those, 2SA and 2SC There are no adjustment points for DC dstasheet in this amp.
