Fred, thanks for the detailed information. Then a similiar thread mentions to “put them in backwards”. Do you already have an account? Share This Page Tweet. I ordered the 2sc as a replacement from MCM.

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? At the time of manufacture, these were considered an excellent choice for a low-noise, small-signal transistor — and were used widely.

Not backwards, or whatever: Yes, my password is: Yankee DogMar 16, Datasheet found a few in my X John. HyperionMar 18, Try the 2SCs you have.

By the early ‘s, the 2SC had 2dc458 itself as a wonderful small-signal, low-noise transistor, again with an acceptable bandwidth, so I began using it as a replacement for the 2SC AndymanJan 4, Is that what you mean by “Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not installed in vintage gear”?


In transistor selection, like many other aspects of electronics, the devil is in the details.

These were based BCE dtaasheet left to right. Yankee DogMar 17, I really want to be sure before I put these things in. Yankee DogMar 15, Things are working and sounding fine. OK, so I am going to replace the leaky 2sc 6 of them in 2xc458 when the new trannys arrive next. HyperionMar 17, 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.

Now I’m just waiting for my caps to arrive so I can breath more solder fumes. You must log in or sign up to reply here.

Sorry it’s hard to describe, but in a way, they do go in backwards sort of. It works fine as a basic, small-signal transistor, and is fine for many applications.

EchoWarsMar 17, Am I hearing more separation or is just because of less noise? I chose it because in the spec manual it was called out as a low-noice small-signal device with a bandwidth not dissimilar to the datashwet, and because the 2SC was used in many machines I encountered — and the device never seemed to fail. I assume that as long as I pay attention to E C B, it will keep me out of trouble like when installing the 2sc when I install the 2sc On the other side the trannys are basically a mirror of the first side preamp board.


No, create an account now.

So, should 2SC’s of any age be replaced anywhere they are found? Yankee DogMar 14, It has a kind of a flat taper on both sides, and printing on both sides, thanks YD.

In or Around the Motor City. What about the data sheets I have posted?

Your name or email address: Unfortunately, they began to leak and generate noise and operating-point errors. I read a thread on this forum that stated something to the effect datasheft the 2sc has “opposite basing” than the 2sc Valley of Heart’s Delight.

Luckily the board was labelled E C B so I just installed them keeping track of that.
