I see some factory built HEADPHONE AMPS pictured in an expensive
audio equipment catalog I get in the mail and they are $300. and up.
Seems like it would be a good project for electronic hobby people to
build themselves. (Small amp: 1 tube or a few transistors? ,power
supply ,2 earphone jacks and a small aluminum box/chassis.). Anyone
have a schematic or ever built one yourself?
