The old ones are now in my ‘rogues gallery’ Thanks again EW: The 2sc’s arrived today and they are installed. I 2sc548 it because in the spec manual it datasehet 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. Luckily the board was labelled E C B so I just installed them keeping track of that.

I ordered the 2sc as a replacement from MCM. Now I’m just waiting for my caps to arrive so I can breath more solder fumes.

Yankee DogMar 14, On the other side the trannys are basically a mirror of the first side preamp board. You must log in or sign up to reply here.


On one side, the transistors go in like normal. Sorry it’s hard to describe, but in a way, they do go in backwards sort of. Fred, thanks for the detailed information. I replace them wherever I find them.

Yes, my password is: Not backwards, or whatever: 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 Satasheet found a few in my X John.

Things are working and sounding fine.

Hitachi Semiconductor – datasheet pdf

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. EchoWarsMar 17, Unfortunately, they began to leak and generate noise dahasheet operating-point errors. The post was made by someone who is well respected and satasheet experienced in this forum, so this is my reasoning for questioning what I have found in the data sheets.

AndymanJan 4, HyperionMar 17, To me it looks like they are the same. So, should 2SC’s of any age be 2ec458 anywhere they are found? Fred LongworthMar 16, Am I hearing more separation or is just because of less noise?

I consider many of these “new 2SC’s” to be counterfeits, i. HyperionMar 18, It looks like a direct drop in.


Then a similiar thread mentions to “put them in backwards”. At the time of manufacture, these were considered an excellent choice for a low-noise, small-signal transistor — and were used widely.

I would never stick it in a low-noise circuit. OK, so I am going to replace the leaky 2sc 6 of them in my when the new trannys arrive next. Log in or Sign up. 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.

Yankee DogMar 16, So looking at the data sheets I am not seeing it. Try the 2SCs you have.

No, create an account now. The issue here is not so much the noise level of the datadheet, but the fact they need to be matched to each other in this situation. A few years ago, “new generation” 2SC’s began appearing.
