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

I mentioned that replacement in the first response. No, create an account now. You can have a TO device that’s good for 50 mA, or one that’s good for 1 amp.

I’lI swap those 4 on power supply. You can pretty much eye-ball this to match.

Karl vd BergApr 19, So polarized your new forward gain would be in the toilet and your Vce sat would be through the roof. You need to match up the power handling ability of the replacement. A couple more came in and then a post about NTE being ok when what they do is buy big loads of leftovers and relabel them.

Is there a particular version of this transistor that is reliable, or are they just all bad and best to get rid of whenever found?


Are there any good versions of the 2SC458?

Also, on the circuit board, and after looking transistot the schematic, each transistor is labeled “TR1” and so on and so forth. These transistors are notorious for becoming noisy and opening. Find all posts by Ebzen.

Need a Teac recapped? There used to be the “U” version, with a higher hFE, but I don’t think Fairchild is making it any longer.

I guess if you live somewhere with a brick and mortar electronics supplier who distributes only NTE and your need is urgent, NTE may be ok It will, however, take gain into the toilet, as you describe. Transistors, where to buy?? If it was translstor in the 70s, change ’em!

Do you already have an account? The 2SC was recommended, and I was going to get them, but Mouser is the only place I could find them, and they won’t get any in stock for 6 weeks. Would like to know for sure if the newer versions should be replaced just because of early samples having isssues. Obviously, this can create problems Last edited by Mark J; at Even a well versed Technician regardless of education can put together a substitution of 4 to 6 parameters that transustor needed to find a replacement.

Authorized servicer for virtually every brand on the planet at one time or another. I concur with Pacific on this as I have used a lot of KSC and they work in more circuits than you think and in other brands as well.

In all my replacements, I have not had any rejections.

Speed can definitely matter. TR14,15 and 16 are the right hand channel designations for the above.

It is not hard to calculate. Yes they are the same. This will cause all sorts of pink noise and crackling. Would you like to see your company or site here? There are some things that are a little bit more difficult. I guess most amp transstor do not use 50mA or more for this size of transistor.
