FS: Headphone amp - best offer

2010-12-20 by Mark Scetta

4-channel LM386-based headphone amp. i made this about 10 years ago and
while it's a little noisy its usage is flexible, fits nicely in 1 rack space,
and it runs off your trusty MOTM power supply. i will include schematics/project notes.

2 stereo unbal. sources:
  • source 1 feeds headphone outputs a,b,c,d (simultaneously)
  • source 2 feeds headphone outputs c,d (simultaneously)

i.e.
  • outs A&B are fed only from stereo source 1
  • outs C&D are switchable source 1 or 2

why i did this i don't know. it works, anyway.

BEST OFFER
shipping from northern California

Thanks for reading
