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

TR14,15 and 16 are the right hand channel designations for the above. You must log in or sign up to reply here.

Stick a fast device in a circuit designed and compensated for a slow one and see what can happen to stability. In terms of thethe is an ideal sub in transisror all circuits I do know of one where it simply doesn’t work, and s are required where they were used. Find all posts by Skywavebe. Need a Teac recapped?

It is not that hard. All sorts of parameters can matter. What about noise performances? 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 Sonics consultant for Transistoe. So I should be able to to put the new KSC in the same exact way?

2SC – 2SC NPN Low Frequency Transistor

Or another place to get the s? My only concern is in circuit that use more than 50mA Ic and in this part I wish it was a little more.


Asside from Akai who else used 2SC’s? A couple more came in and then a post about NTE being ok when what they do transixtor buy big loads of leftovers and relabel them.

This will cause all sorts of pink noise and crackling. It transitsor depends on what you call a category so the list could be more but the idea is that a replacement, at least electrically, can more often than not be obtained from a wide transsitor of transistors.

For the matter of pin outs I have installed a lot of KSC in place of 2SC and never had a problem other then flipping them in the holes.

2SC458 – 2SC458 NPN Low Frequency Transistor

If the device is supposed to have a forward gain of sayso configured your realized forward gain might be 6 or 7. So I will be carefully replacing one by one and putting in the new ones the same exact way.

What do you think? I’lI swap those 4 on power supply. You must log in or sign up to reply here. Skywavebe Skywave Tape Deck Repair. 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.


In the world of repair, we often times have to use substitute transistors. Obviously, this can create problems Transistors, where to buy??

The best version currently is labeled KSCF. For subjects related to tape itself, see the Open Reel subforum under this one. Find all posts by Mosesmunoz. If you do not like NTE then use another sub. 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.

Would you like to see trransistor company or trajsistor here? I have the ‘s that have the flat top and not the slant top ones. Last edited by Mark J; at Do you already have an account?

Hi All, total noob here but wanted to confirm something before I actually start replacing these transistors on my Akai GXd. For example Saul Marantz loved to take advantage of semiconductor characteristics and would supply characterized devices as trnasistor.
