12:49 <Greys> then once he's fixed the amp he jams out a bit

12:50 <Greys> he does skip out on actually performing the repairs, but we've got Clive for that

12:52 <Greys> so far I've learned that in audio circuits like this, certain faults can result in just about anything becoming "microphonic", like he'll tap on a resister and get sound out of the speaker

12:56 <Greys> gotta love how most of the amps he works on have at best four colors of wires, but frequently just one, and a hundred or two 3" lengths of wire

13:04 <Greys> also I've learned about "tremolo roaches", which are an early kind of optoisolator composed of I believe a neon or resistive lamp and a photosensitive resistor; just shrinkwrapped together

16:54 <Greys> if something is non-euclidian, what are the options of things that it might actually be?
