Thanks Avionic, but have you used or ever ordered one of these from them? San Francisco Bay Area. Do you already have an account?

The NTE43 appears to be no longer available as a replacement plus comments on this forum tell me to steer clear of NTE. You can heatshrink the tops together to for thermal contact if you want to be thorough. Is There a Replacement? YES but NTE parts for most of us in doing reputable repairs and restorations are an absolute begruggingly last resort. Halisson and Rodrigan like this.

It seems it’s not easy to find this part in ChrisMarantzJan 11, OverLoadJul 27, I see now that they are available, if in a somewhat limited fashion. Do you know any newer replacement?


Double Transistor 2SA798: Is There a Replacement?

I find it hard to trust a product listing with no description, data sheet or even a lousy picture. It shouldn’t be that difficult to find these or 2SA equivalentor even pulled parts enexpensively, just pay attention to the last letter if the manual has specifications for that. AngelRaJul 27, Yes, my password is: Log in or Sign up. I have stocked up on a couple just in case.

By placing two transistors together and melding their emitters, would this be a possibility for a replacement should none exist.

This has been an excellent thread for me. Quite possibly they were the real thing. I thought to look for a replacement, just in case and came up empty everywhere I looked. No, create an 2wa798 now.

2SA798 Datasheet

Any comments on taking this route? I have removed it and replaced it on the boards a total of four times now and it is getting a little beat looking, to the point that I fear to have to test it or remove it again.


You must log in or sign up to reply here. Thanks to all for your responses and PMs. Question one is does anyone know of a replacement for this transistor? If this is a viable solution can someone supply the part number of the transistor needed to make a twin setup? I realize this is an old post from way back when but I find myself in need of a couple of these 2SA transistors.

Use a pair of matched KSA It won’t be a good idea to use two separate transistors in this case. NTE43 replaces the 2sa KingBubbaFeb 13, I have 2sq798 of some suppliers that I have never heard of before and that is a good thing. Other comments and suggestions are, of course, still welcomed. At this time, I do not need the item in question but was rather testing the waters in case I do.
