This is the same project that is on Rod Elliot's site.....
....but I used a 12v relay rated for lower current (1 amp), and added headphone jacks, instead of speaker terminals. Power is from a 9v or 12v DC wall wart.

I'm finishing it tonite, so I'll discover if I can hear a difference between two almost identical amps I built (they use different opamps)...and compare some other amps as well.
Amp Mash-Up.
Outputs will come from my 'puter's soundcard, an RME 9632 hammerfall, with
optional analog daughter board, (4 extra identical in/outs). The output gain
on the amps will be matched by .....well I not sure of specifics yet, I'll post back with those, and tell you my listening results as well.
