I used to have a Sony cassette recorder in the early 80s that if you
wore headphones and pressed record, you could literally here a pin
drop in the room. I took this apart back then and the circuit for this
used a 741 op amp chip. I have some of these and have found some
schematics and put them together on my breadboard, but none of them
have the gain that the cassette recorder had. Does anyone have a
schematic that will produce this high gain?
