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 understand now why I was confused on how to place the transistors. HyperionMar 18, You must log in or sign up to reply here. These were based BCE reading left to right. The original 2sc does look different.
Your name or email address: To me it looks like they are the same. A few years ago, “new generation” 2SC’s began appearing. No, create an account now.

Share This Page Dztasheet. OK, so I am going to replace the leaky 2sc 6 of them in my when the new trannys arrive next. I used BC as the replacement in my X – they work just fine. Yes, my password is: HyperionMar 17, It has a kind of a flat taper on both sides, and printing on both sides, thanks YD.
I would never stick it in a low-noise circuit. So looking at the data sheets I am not seeing it.
Then a similiar thread mentions to “put them in backwards”. Log in or Sign up. I replace them wherever I find them. Do you already have an account? They simply aren’t to be trusted.

I ordered the 2sc as a replacement from MCM. Yankee DogMar 15, EchoWarsMar 17, Fred, thanks for the detailed information. Unfortunately, they began to leak and generate noise and operating-point errors. Now I’m just waiting for my caps to arrive so I can breath more solder fumes. 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. On the other side the trannys are basically a mirror of the first side preamp board.
I really want to be sure before I put these things in.
What about the data sheets I have posted? So, should 2SC’s of any age be replaced anywhere they are found? Try the 2SCs you have.
Am I hearing more separation or is just dataseet of less noise? Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not installed in vintage gear.
I read a thread on this forum that stated something to the effect that the 2sc has “opposite basing” than the 2sc Things are working and sounding fine.

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 datasheeet. Trannys are in 2sc and it sounds a little sharper, and clearer if that means anything. 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 datashee back.
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. 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 At the time of manufacture, 2zc458 were considered an excellent choice for a low-noise, small-signal transistor — dataeheet were used widely.
I found a few in my X John. Sorry it’s hard to describe, but in a way, they do go in backwards sort of. Not backwards, or whatever: Fred Longworth datashert, Mar 16, EchoWarsMar 18, Valley of Heart’s Delight. 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 working fine, but, it looks like I’ll be pulling them.
The 2sc’s arrived today and they are installed. Is that what you mean by “Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not datashete in vintage gear”? On one side, the transistors go in like normal.
