HyperionMar 17, Valley of Heart’s Delight.

Then a similiar thread mentions to “put them in backwards”. 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?

I found a few in my X John. I really want to be sure before I put these things in. They simply aren’t to be trusted. No, create an account datashete.

The old ones are now in my ‘rogues gallery’ Thanks again EW: Fred, thanks for the detailed information. Try the 2SCs you have. Am I hearing more separation or is just because of less noise? EchoWarsMar 18, Do you already have an account?

So looking at the data sheets I am not seeing it. Log in or Sign up. Fred LongworthMar 16, What about the data sheets I have posted? Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not installed in vintage gear. 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. I read a thread on this forum that stated something to the effect that the 2sc has “opposite basing” than the 2sc 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 used BC as 2s4c58 replacement in my X – they work just fine.

I would never stick it in a low-noise circuit. Sorry it’s hard to describe, but daatsheet a way, they do go in backwards sort of. So, should 2SC’s of any age be replaced anywhere they are found? Unfortunately, they began to leak and generate noise and operating-point errors. In transistor selection, like many other aspects of electronics, the devil is in the details.

It has a kind of a flat taper on both sides, and printing on both sides, thanks YD. A few years ago, “new generation” 2SC’s began appearing. Yes, my password is: Yankee DogMar 14, Your name or email address: The original 2sc does look different.

By the early ‘s, the 2SC had proved 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 I did pay attention to the circuit board with the location 2zc458 E C B and put the legs of the 2sc in the apropriate holes, and unit is working fine, but, it looks like I’ll be pulling them. The 2sc’s arrived today and they are installed.

Share This Page Tweet. AndymanJan 4, Not backwards, or whatever: On the other side the trannys are basically a mirror of the first side preamp board.

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. Now I’m just waiting for my caps to arrive so I can breath 2sc4588 solder fumes.

It works fine as a basic, small-signal transistor, and is fine for many applications. Yankee DogMar 15, I consider many of these “new 2SC’s” to be counterfeits, i. 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 It looks like a direct drop in.

HyperionMar 18, These were based BCE reading left to right. Luckily the board was labelled E C B dataseet I just installed them keeping track of that.
