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

Infamous 2SC Transistors – Tapeheads Tape, Audio and Music Forums

I suppose that there may be special cases in audio signal handling but it is generally safe to say that trznsistor there are only about five different transistor categories that all transistors can be placed in.

There are switching applications and RF applications, microwave, and more. With all the information available via the interweb, I’ve rarely run into a situation in which I couldn’t find a reasonable 2sv458 from a higher-quality maker. These transistors are notorious for becoming noisy and opening. The has been discontinued by the manufacturer, so if you DO find them, stock up.

Find all posts by johns It just takes a little time.

The KSC previously suggested is perfect too. Ah, Tranwistor see you are not saying that. Amen as regards the NTE devices. Do you already have an account? It will, however, take gain into the toilet, as you describe. Obscure service subjects that don’t quite fit go in the Help and Do It Yourself subforum.


Bought them at the shop near home for. Reel To Reel All discussions pertaining to reel to reel decks. N8NagelDec 27, They told me that the are not longer available and that a good replacement transkstor the japanese 2sc Sonics consultant for Denon. Is there another replacement for the s? Karl vd BergApr 19, The best version currently is labeled KSCF.

TR14,15 and 16 are the right hand channel designations for the above. Transisto you do not like NTE then use another sub. Pacific Stereo Sendust for brains. It is not that hard.

Maybe will replace the 4 I have on power supply: Ok so I just got the KSC transistors in and according to the data sheet they are ECB from left to right with the flat part facing you. In my quest to fix my x, I am replacing the 2SCs. The replacement will need to mechanically fit and will therefore be about the right size suggesting its power dissipation capabilities. I guess most amp circuit do transitor use 50mA or more for this size of transistor.

That’s very much oversimplified.

And they are pricey. Last edited by Ebzen; at Your name or email address: My only concern is in circuit that use more than 50mA Ic and in this part I wish it was a little more. Hi All, total noob here but wanted to confirm something before I actually start replacing these transistors on my Akai GXd. Hell if I remember right the replacements for 2SC have reversed pins compared to the older ones.

2SC458 – 2SC458 NPN Low Frequency Transistor

transistot Would like to know for sure if the newer versions should be replaced just because of early samples having isssues.

So I will be carefully replacing one by one and putting in the new ones the same exact way.

There are some things that are a little bit more difficult. No, create an account now. If the device is supposed to have a forward gain of sayso configured your realized forward gain might be 6 or 7. Also I don’t think I will replace those 15 pcs of 2SCs in the tuner. Find all posts by BarryC Log in or Sign up. I noticed that there is one end of the three point pin connection and has a white filled in square. Dissipation and safe operating area can vary widely in the same package types.
