I have not searched the other parts mentioned in this thread, but also with web search i didnt found a “recommended” replacement. But that will not last for ever. Looking at the noise figure curves adtasheet source impedance and current density here javascript: Is there any equivalent for this? Looking forward to some results!


June 06, The -E parts are higher beta than the -D. The original 2sb and 2sD were designed for moving coil dwtasheet amps with ohm nominal source impedance, so arguably better than needed for ohm source impedance microphones. You are about to become the voice of Interplanetary Parliament. Rossi probably knows more than I do about what folks are using these days. Hi all, looks like two of the channels of my mixing console were fried when a phantom power coupling capacitor blew up.

Transistor substitution in GAR April 01, The original Rohm transistors are discontinued; if you can’t source any, try the 2SA or, not quite as low noise but still pretty good, 2N But look 2ssc2274 the data sheets for NF ddatasheet impedance curves, for something that doesn’t suck into ohms. Bookkeeper Member Czech Republic Posts: I don’t remember what transistor Peavey switched to.

But I wouldn’t change it here for two reasons. Very nice that Mr.

Maybe they have REAL much in stock. February 26, I typically would have run the 2sb at a little higher current density. I usually added clamp diodes backwards across the be junction of the low noise devices to make sure they datasheeet zener if reversed, as that can make them noisy.

The 2SA from Toshiba is an excellent super low Rbb transistor, but it has become scarce.

March 29, Other observations about the schematic, the diode across the uF looks a little odd. Thank you very much In the schematic there are 2 2sb Those are super low Rbb transistors for low Z input stages.


Maybe he, or another ilumanted member of this forum can bring some other substitutes! I was already off the reservation when Peavey made their lifetime buy on that.

I also want to know if there is a good modern replacement for the 2sb out there. I looked around briefly this afternoon datsaheet didn’t see anything obvious It will work but you’ll have more noise.

Perhaps they are protecting against some latch up condition. A am wondering what Midas is using or their XL42 preamp now.

Rossi Member Germany Posts: Yup, they have been obsolete for years. Low noise dwtasheet are generally graded for beta, as in the more beta the better for low noise applications. Hi Have these transistors in bad Delta channel.
