Ruby Doobie....deux

Postby pinkjimiphoton » 16 Apr 2017, 03:34

so i was dickin' around with my ruby doobie and wondered if i could get away with bridging 2 lm386 chips... and, well.... this happened. i know the preamp part is good. i haven't built the power amp part yet, but in the spirit of a 10 toed opposable thumbed monkey with a breadboard, figured i'd draw it up and lay it out. anybody see mistakes? suggestions? redundant stuff? not sure if i still need the 220u electro on the positive speaker output. i believe everything else should be good.
the "gain" pot should be a dualie, so it can adjust gain on both chips. or ya could just say screw it, and put a cap there instead... anywhere from 47n to 4.7u apparently should work.
ideas? comedy? suggestions? criticisms? plagiarism? solipsism?anyism?
don't hold back, now.
IF ANY BRAVE SOUL DARES TO TRY THIS FOOLHARDY THING ON THE BREADBOARD, LET ME KNOW!! it may be a while before i can verify it.
too much shit on my bench!!!
