Okay I'm totally wrong (again) please accept my sincere appologies. We all have our off days. Tomorrow is a new day. :smile: To all so far, Thanks for all the help, conjecture, pointers, lessons and schematics. Due to work, family and the looming holidays, I probably won't get to any construction u...

Bigglez and Steve, Okay, I saw the statements about gain previously, but seeing as how it had been very late when I was reading those, they didn't register until now. Steve, yours is 100 (10k/100), and mine is 5 (10k/2k). Bigglez, In changing the gain like that, how would that affect the base bias s...

Bob, About 1/2 as many 06's as 04's, a few 2n2222's and assorted others. Starting super simple and will move up later. Yeah, op-amps will be coming soon enough, but for now I want to use as much on hand stock as possible. I thought about that reason when it was pointed out by Steve (C1 direction). A...

I almost forgot to mention, one of my suggestions was to connect a resistor in series with C3 (the emitter bypass cap). MrAl, I ran some sims using your values and they seem to work very well in this circuit, except for the C3/series resistor. That really put the kabosh to pre-amp. Removing the res...

Mic Pre-Amp
Many of you will recall the thread started by brodave38 about amplifying headphone output. Near the end I sort of took over, so I wanted to move my project to a new thread. My son has taken up guitar - working on his 2nd year now - and he has really come along. As anyone who has ever gotten fairly g...

Disaster or not, yours is a fully functional site. Many of the sites either don't exist or are so disabled as to be just the index page. Some of those that don't exist have been victims of the ever changing webhost scene, such as AOL, XOOM, etc., others seem to have just been let go for whatever rea...
