- Well you could try using an LM301 and a an LM386 in
- conjunction. The 301 you can hook up to boost say 1-1000 in
- gain and the 386 you can set up for 20. This will give you
- a range of 20 - 20000 in gain. That good enough? :) Now if
- you are talking micro volt levels it's a whole new ball game.
