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

This will cause all sorts of pink noise and crackling. Need a Teac recapped? Try sticking your substitute in one of those types of circuits and see what your results are. Guys, I have a whole forest of them on my tuner board: For one, I don’t see how reversing collector and emitter changes the polarity of the device.

Find all posts by johns Uncategorized Help and Do It Yourself. Then they post up a substitution list and buyer beware, sometimes they aren’t close and don’t work.

The has been discontinued by the manufacturer, so if you DO find them, stock ttansistor. And it also seem to be part of most “repair” kits you can buy on the internet for those machines. Find all posts by Ebzen. Not the same gear you’re working on, but the thread is here. Frusciante89Apr 19, Mark J Burning Tape. Obscure service subjects that don’t quite fit go in the Help and Do It Yourself subforum. In addition, some devices are better suited to some types of tasks and toplogies in terms of noise.


Your name or email address: All bad, no questions. Obviously, this can create problems Don’t worry, virtually every transistors are better than the 2SC Replace it with a 2sc or 2sc Probably best to do just one channel first and then test it’s ok hopefully and then do the other channel just in case of any errors. It had different mounting but finding TO transistors these days might be more trouble than it is worth. No, create an account now. If it was 2xc458 in the 70s, change ’em!

You must log in or sign up to reply here. I was wondering the same thing about the ‘s, they were common in the early to mid 70’s but the other day I transistoe a tuner from the early 80’s opened and noticed it had the newer ‘s in it. Is there another replacement for the s? These transistors are notorious for becoming noisy and opening.

DetailmanJan 1, KentTeffetellerJul 16, I don’t know why they called the 2SC a low noise transistor since the noise contour map of the 2SC shows that it is much noisier than many transistors. Valley of Heart’s Delight.

Yes, my password is: For example, the common 2SC is much better. Transistors, where to buy?? Do you already have an account?


But, most importantly, general purpose applications are the most common. It is not that hard. I bought it at MCM I think. Would you like to see your company or site here? Authorized servicer for virtually every brand on the planet at one time or another.

2SC – 2SC NPN Low Frequency Transistor

TR14,15 and 16 are the right hand channel designations for the above. Originally Posted by Mosesmunoz. For the matter of pin 2s458 I have installed a lot of KSC in place of 2SC and never had a problem other tranxistor flipping them in the holes. Your name or email address: ElectoneJul 16, These include general usage, recording, playback, and service questions.

No 2sc4458 factors allowed here For example Saul Marantz loved to take advantage of semiconductor characteristics and would supply characterized devices as replacements. Maybe will replace the 4 I have on power supply: Ah, I see you are not saying that. Pacific Stereo Sendust for brains. There are switching applications and RF applications, microwave, and more. I guess most amp circuit do not use 50mA or more for this size of transistor.
