Trannys are in 2sc and it sounds a little sharper, and clearer if that means anything.

I really want to be sure before I put these things in. It works fine as a 2ssc458, small-signal transistor, and is fine for many applications. Yankee Dog xatasheet, Mar 15, EchoWarsMar 17, The post was made by someone who is well respected and very experienced in this forum, so this is my reasoning for questioning what I have found in the data sheets.

The original 2SC was made by Hitachi, and installed in a funny-looking rectangular package with a little “roof” on the top that slopes down from front to back. 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.

OK, so I am going to replace the leaky 2sc 6 of them in my when the new trannys arrive next.

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 eatasheet the correct Digikey part? 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 Fred Longworth datashdet, Mar 16, So looking at the data sheets I am not seeing it.

Do you already have an account? On one side, the transistors go in like normal. I would never stick it in a low-noise circuit. In transistor selection, like many other aspects of electronics, the devil is in the details. A few years ago, “new generation” 2SC’s began appearing.

Unfortunately, they began to leak and generate noise and operating-point errors. Things are working and sounding fine. Not backwards, or whatever: Luckily the board was labelled E C B so I datasneet installed them keeping track of that.

Sorry it’s hard to describe, but in a way, they do go in backwards sort of. Yankee DogMar 14, Now I’m just waiting for dagasheet caps to arrive so I can breath more solder fumes. To me it looks like they are the same. What about the data sheets I have posted?

Am I hearing more separation or is just because of less noise? It has a kind of a flat taper on both sides, and printing on both sides, thanks YD. I found a few in my X John.

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. Then a similiar thread mentions to “put them in backwards”. It looks like a direct drop in. So, should 2SC’s of any age be replaced anywhere they are found? Try the 2SCs you have. On the other side the trannys are basically a mirror of the first side preamp board.

I read a thread on this forum that stated something to the effect that the 2sc has “opposite basing” than the 2sc I used BC as the replacement in my X – they work just fine. The 2sc’s arrived today and they are installed.

They simply aren’t to be trusted. Yankee DogMar 16, Fred, thanks for the detailed information.
