New other see details. This is very educational and fun for me. OverLoadJul 29, BinaryMikeJul 29, Please provide a valid price range. Rds On Max Id, Vgs The 2sb has a higher voltage rating, and the is rated at higher current.

All Auction Buy It Now. 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. Item Location see all.

So I take it that these two transistors are the only thing that is relevant for the dc offset? How do you get matched pairs of transistors normally? 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. No matter where I put the probes, I get continuity.


For parts or not working. Man, it is difficult to find these output transistors. Without more info it’s hard to say what was original. I guess I’m going to have to go with those, but I’ve gotten the impression that they are not entirely suitable.

It arrived today, and now the amp works again. Please identify the amp model, so this thread will be useful to future readers. Now, with your insight, I looked again and found something of great interest! Buying Format see all. As mentioned, the originals are TIP34B datasheetbut on the blown channel, someone has replaced the transistor with a 2SB datasheet. Guaranteed Delivery see all. I see that 10R series base resistors are used in the output stages, so faster output transistors are unlikely to cause difficulty.

And finally, 2SC or 2SC Can be found at most electronic distributors. Guaranteed 3 day delivery. Designed for general-purpose power amplifier and switching applications. BinaryMikeAug 4, Skip to main content. RuxmanAug 4, The original output transistors were TIP34B, and I need replacements but they seem to be impossible to find.

This device is a low level audio amplifier and switching transistor, and can be used for analog switching applications.

Maximum Reverse Leakage Current: If I try anyway, do you still think that maybe the DC daatsheet would be improved?


If it’s clean, then overall amp performance is likely to be improved.

It’s an OEM amp TIP33 and 34 are still available – should use the “C” version v. Maybe that is why it has been smoked? Sub Category Line Driver or Receivers.

Back to original question. Or is this caused by another part in the circuit? Log in or Sign up. I have an amp with a blown channel. BinaryMikeAug 1, Guaranteed by Mon, Jan 7. I ordered a new TIP transistor before starting this thread.

Any help would be really appreciated! However, the DC offset is very high. This Buy It Now is for 15 buffers. Tip 35C and 36C are higher powered versions and are still available.
