I will order replacement transistors for all but only replace those that need The 2SC’s are used in both the pre-amp and main amp, if that. Hi All, total noob here but wanted to confirm something before I actually start replacing these transistors on my Akai GXd. Local electronic. 2SC, NPN 2SC, 2SC NPN Low Frequency Transistor, buy 2SC

Need a Teac recapped? Those who have studied EE can easily resolve this problem in that the parameter of transistors is part of the course usually. Also, on the circuit board, and after looking at the schematic, each transistor is labeled “TR1” and so on and so forth.

Typically 2SC or 2SD transistors can be found inside the same line to work or if you like to determine the match yourself, you can do that. Sorry for all the questions, just thought figured I would ask all you tech savy veterans! I have the ‘s that have the flat top and not the slant top ones. Find all posts by johns Are there any good versions of the 2SC? No, create an account now. I was wondering the same thing about the ‘s, they were common in the early to mid 70’s but the other day I had a tuner from the early 80’s opened and noticed it had the newer ‘s in it.


Not the same gear you’re working on, but the thread is here. The noise floor on the is a bit better I don’t have any test gear than the As to the install so that the EBC matches, research this, mark your board, know that the slant faced s used the side opposite the writing as the front when you look at the data sheet and the new ones use the writing face as the front.

You could invert the device pretending the emitter is the collector and the collector is the emitter and it would work with EXTREME limitations. For example, the common 2SC is much better. It is not that hard.

I replaced the C with BC Find all posts by Ebzen. But for general repairs and something that is for background listening the is fine. TR14,15 and 16 are the right hand channel designations for the above. ElectoneJul 17, Amen as regards the NTE devices.

Find all posts by Pacific Transistr. You need to match up the power handling ability of the replacement.

Except a KSC, which is a lower-noise part and a lot cheaper. When a guide is not available- and there are often times many available, then a Technician has to find out the parameters of the original transistor and then find one tranistor would be better or equal to that one.

They told me that the are not longer available and that a good replacement is the japanese 2sc In terms of thethe is an ideal sub in almost all circuits I do know of one where it simply doesn’t work, and s are required where they were used.

I found this quote from a thread by jpdylon, a really good trandistor. Find all posts by Mark J. Last edited by Ebzen; at There are some things you must absolutely match up. According to the google hitachi data sheet I found for the 2SC, it seems it is also has the same ECB from left to right. If they don’t give trouble, eventually they will.
