@fahey- hey there isnt a chassis. the closest thing i have to a chassis is the metal that the pot knobs will stick through when i get this thing working. the green wire gets really hot. i burned the carpet a little.

yes the piece of iron is screwed into the side of a wooden cab

@phatt- ill check it out
@fahey- its screwed into the side of the amp-would the green wire need to be grounded to the same thing the board is grounded too. ie the face plate?

hey i got the led to light up but i cant get anything but hum.
http://www.shedradios.com/images/crate_cr-112_04.jpg

at the vcc+ im getting 44 v. almost double the 24 thats supposed to be coming to the IC 2. the only thing before the IC 2 is a 5% 1w R and a led.
ive got 44v going to IC1 also. IC 1 and 2 are supplied by the same trace. could this be a grounding issue? help

hey guys, the 127 was in backwards. now i need to find a piece of steel to attach the green wire to. i almost burned a hole in the carpet.

its kind of dissapointing that i cant make this a 212. ill save the other speaker for another amp i guess.
thanks for your help
