tried trying the mentioned mic preamp circuit above got bad results. only results to noise and now voice/ whatsoever being picked up...what would be the prob??? or maybe the gain's not that high? tried simulating it and got about 3~4 gain lvl....

followup: used a 2-lead electret condenser mic 60Hz...is this gud enough??...tnx...

Please stay in a single thread.
I answered why your preamp doesn't work in your other thread about it.

EDIT: Your other thread was at Electro Tech Online where you posted the schematic.
