They simply fatasheet to be trusted. The original 2sc does look different. 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 datadheet seemed to fail.

Luckily the board was labelled E C B so I just installed them keeping track of that. In transistor selection, like many other aspects of electronics, the devil is datashheet the details. HyperionMar 17, It works fine as a basic, small-signal transistor, and is fine for many applications. Datashset of Heart’s Delight. Fred LongworthMar 16, Unfortunately, they began to leak and generate noise and operating-point errors. It looks like a direct drop in.

I found a few in my X John. On the other side the trannys are basically a mirror of the first side preamp board. I understand now why I was confused on how to place the transistors.

In or Around the Motor City.


I used BC as the replacement in my X – they work just fine. I ordered the 2sc as a replacement from MCM. The old ones are now in my ‘rogues gallery’ Thanks again EW: The post was made by someone who is well respected and very experienced in this forum, so this is my reasoning for questioning what Datasueet have found in the data sheets.

Yes, my password is: OK, so I am going to replace the leaky 2sc 6 of them in my when the new trannys arrive next. The 2sc’s arrived today and they are installed.

Yankee DogMar 17, These were based BCE reading left to right. I would never stick it in a low-noise circuit. 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.

HyperionMar 18, I replace them wherever I find them. No, create an account now. It has a kind of a flat taper on both sides, and printing on both sides, thanks YD. 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.


I consider many of these “new 2SC’s” to be counterfeits, i. AndymanJan 4, So, should 2SC’s of any age be replaced anywhere they are found?

Not backwards, or whatever: So looking at the data sheets I am not seeing it.

By the early ‘s, the 2SC had proved itself as a wonderful small-signal, datashfet transistor, again with an acceptable bandwidth, so I began using it as a replacement for the 2SC Log in or Sign up. Now I’m just waiting for my caps to arrive so I can breath more solder fumes.

Yankee DogMar 14, I read a thread on this forum that stated something to the effect that the 2sc has “opposite basing” than the 2sc On one side, the transistors go in like normal. EchoWarsMar 17, 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 assume that as long as I pay attention to E Adtasheet B, it will keep me out of trouble like when installing the 2sc when I install the 2sc
