Hello everyone I'm having a problem with a series 1 mic pre (just the mic pre, line in is fine). I'm getting a lot of noise and extremely distorted signal. Everything looks fine visually. I swapped the chip and that didn't fix it. My next thought was that it could be caused by a bad transistor on the front end of the circuit. So I did a little looking and now I'm a bit confused.
It seems that I need either of these transistors: 2SAB737, 2SA991, or 2SA1084 I'm sure their are others but this is what is in my console and the 2SA1084 was written in some of the documentation that I have. Does anyone have a lead on where these can be sourced or other replacement options? Also what is the best way to match them? Can it be a simple DMM hFE test? Also maybe I'm going down the wrong path, any other thoughts about what could be causing this? Sorry for the long post, Thanks, Jared ------ View the list online at: http://www.mail-archive.com/[email protected] You can unsubscribe at anytime by sending an email to mailto:[email protected] with "unsubscribe neotek" in the message body.
