This is correct, and a lot of the "pre-amped" microphones or very
good and some or not. I used an old dynamic microphone case and pulled the
guts out of it. It had been in a flood. Then built a preamplifier and
condenser microphone on a small PC board and installed it in the old
microphone case. I actually used two condenser microphone cartridges from
Radio Shack. I don't remember the number but they were about dime size
round and thick. I think I used three transistors but I don't remember the
circuit as that was several years ago. My wife, Vickie, helped dye the new
spit cloth and glued it in.

The LEDs were a small optical add-on.
