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.

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. Yankee DogMar 15, I understand now why I was confused on how to place the transistors. Valley of Heart’s Delight. Then a similiar thread mentions to “put them in backwards”. A few years ago, “new generation” 2SC’s began appearing. What about the data sheets I have posted?
Yankee DogMar 16, Sorry it’s hard to describe, but in a way, they do go in backwards sort of. Unfortunately, they began to leak and generate noise and operating-point errors. I consider many of these “new 2SC’s” to be counterfeits, i.
So looking at the data sheets I am not seeing it.
Am I hearing more separation or is just 2dc458 of less noise? I replace them wherever I find them. 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 Luckily the board was labelled E C B so I just installed them keeping track of that.
To me it looks like they are the same. In or Around the Motor City.

By the early ‘s, the 2SC had proved itself as a wonderful small-signal, low-noise transistor, again with an acceptable 22sc458, so I began using it as a replacement for the 2SC Fred, thanks for the detailed information. The old ones are now in my ‘rogues gallery’ Thanks again EW: The 2sc’s arrived today and they are installed. HyperionMar 17, Fred LongworthMar 16, So, should 2SC’s of any age be replaced anywhere they are found? You must log in or sign up to reply here.
On the other side the trannys are basically a mirror of the first side preamp board. 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. Is that what you mean by “Some new-production 2SC’s have the same basing as the 2SC, but those new devices are not datashheet in vintage gear”?
Try the 2SCs you have.
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. It has a kind of a flat taper on both sides, and printing on both sides, datasneet YD.
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 ordered the 2sc as a replacement from MCM. At the time of manufacture, these were considered an excellent choice for a low-noise, small-signal transistor — and were used widely. Trannys are in 2sc and it sounds a little sharper, and clearer if that means anything. I found a few in my X John.
