Thank you for the update – I found 2 – they looked so odd I checked up on them – particularly here on AK, and found them pretty much regarded as the spawn of the devil himself. It looks like a direct drop datahseet. Log in or Sign up.

I did pay attention to the circuit board with the location of E C B and datasheef the legs of the 2sc in the apropriate holes, and unit is working fine, but, it looks like I’ll be pulling them. I replace them wherever I find them. EchoWarsMar 18, A few years ago, “new generation” 2SC’s began appearing.


Not backwards, or whatever: Your name or email address: Yankee DogMar 17, Trannys are in 2sc and it sounds a little sharper, and clearer if that means anything. I would never stick it in a low-noise circuit. AndymanJan 4, Fred LongworthMar 2c458, Now I’m just waiting for my caps to arrive so I can breath more solder fumes.

I understand now why I was confused on how to place the transistors. These were based BCE reading left to right.

Luckily the board was labelled E C B so I just installed them keeping track of that. Yankee DogMar 16, I found a few in my X John.

I used BC as the replacement in my X – they work just fine. Unfortunately, they began to leak and generate noise and operating-point errors.

No, create an account now. On the other side the trannys are basically a mirror of the first side preamp board. Fred, thanks for the datahseet information.


I ordered the 2sc as a replacement from MCM. In transistor selection, like many other aspects of electronics, the devil is in the details.

Then a similiar thread mentions to “put them in backwards”. Try the 2SCs you have. They simply aren’t to be trusted.

I’m trying to buy some 2SC transistors from Digikey or Mouser, but am not having any success at all with this part number to replace my 2SCs can anyone recommend an alternate, or, better still the correct Digikey part? 2sc58, should 2SC’s of any age be replaced anywhere they are found?
