Hi Have these transistors in bad Delta channel. But I wouldn’t change it here for two reasons. Looking forward to some results!
They were using truck loads of the 2sd Datasneet version. The -E parts are higher beta than the -D. February 18, I have not searched the other parts mentioned in this thread, but also with web search i didnt found a “recommended” replacement. One weak link sonically for that design is the uF cap in the gain leg Roberts joins the thread!
Started by abby normal The Lab. Bookkeeper Member Czech Republic Posts: March 29, I typically would have run the 2sb at a little higher current density. Those are super low 2xc2274 transistors for low Z input stages.
So I’d drop them in and see how it works. I don’t remember what transistor Peavey switched to. That design looks like around 1 mA nominal set by ohm and Vbe of 2sc In the schematic there are 2 2sb I also want to know if there is a good modern replacement for the 2sb out there. Perhaps they are protecting against some latch up condition. August 16, April 01, I was already off the reservation when Peavey made their lifetime buy on that.

I’ve used the npn counterpart 2SC with good results. Maybe he, or another ilumanted member of this forum can bring some other substitutes! Rossi probably knows more than I do about what folks are using these days. You probably have two of those per mic input. Regular transistors will be noisy in this application; I don’t know the NTE part, but I doubt it is a super low Rbb part. Change both transistors in the input stage. Rossi Member Germany Posts: The 2SA Hitachi that I pointed out datxsheet is a popular replacement used in quite a few preamp stages that previously had the 2SB Started by jrmintz The Lab.

If you sprinkle when you tinkle, please be neat and wipe the seat. It will work but you’ll have more noise.
The number sounds familiar Low noise devices are generally graded for beta, as in the more beta the better for low noise applications.
Just to get the channel working you could probably parallel up a few 2n per, but longer term you want datassheet use a proper low noise part. Hi all, looks like two of the channels of my mixing console were fried when a phantom power coupling capacitor blew up.
