Your name or email address: 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”?
It works fine as a basic, small-signal transistor, and is fine for many applications. These were based BCE reading left to right. On one side, the transistors go in like normal. To me it looks like they vatasheet the same. Unfortunately, they began to leak and generate noise and operating-point errors.
I understand now why I was confused on how to place the transistors. In transistor selection, like many other aspects of electronics, the devil is in the details.
I did pay attention to the circuit board with the location of E C B and put the legs of the 2sc in the apropriate holes, and unit is datasheey fine, but, it looks like Datawheet be pulling them. EchoWarsMar 18, At the time of manufacture, these were considered an excellent choice for a low-noise, small-signal transistor — and were used widely.
HyperionMar 17, I read a thread on this forum that stated something to the effect that the 2sc has “opposite basing” than the 2sc You must log in or sign up to reply here. Log in or Sign up. The old ones are now in my ‘rogues gallery’ Thanks again EW: Valley of Heart’s Delight. The original 2sc does look different.
On the other side the trannys are basically a mirror datashret the first side preamp board. Then a similiar thread mentions to “put them in backwards”. What about the data sheets I have posted?

Trannys are in 2sc and it sounds a little sharper, and clearer if that means anything. So, should 2SC’s of any age be replaced anywhere they are found?
Yankee DogMar 16, It looks like a direct drop in. 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 has a kind of a flat taper on both sides, and printing on both sides, thanks YD. Am I hearing more separation or is just because of less noise? I used BC as the replacement in my X – they work just fine. Yankee DogMar 17, Yankee DogMar 15, I replace them wherever I find them. 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 2SC, and because the 2SC was used in many machines I encountered — and the device never seemed to fail.
Fred LongworthMar 16, The issue here is not so much the noise level of the transistor, but the fact they need to be matched to each other in this situation. AndymanJan 4, 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?
A few years ago, “new generation” 2SC’s began appearing.

Not backwards, or whatever: Fred, thanks for the detailed information. I would never stick it in 2sv458 low-noise circuit.
Things are working and sounding fine. 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 The 2sc’s arrived today and they are installed. I ordered the 2sc as a replacement from MCM. EchoWarsMar 17, Yankee DogMar 14, Luckily the board was labelled E C B so I just installed them keeping track of that. I really want to be sure before I put these things in. I found a few in my X John.
