lol. yeah, I definately learned a few things for next time... like get metal jacks, and I wish I had a drill press... lol.
I did notice that my amp pops when I turn it on and off. When I read the troubleshooting on tangent's site he said that it is probably caused by dc offset or something like that.
however, I measured from the IG to the outputs and didn't get hardly anything.
with my multimeter set to 2000m DC it read about 6, which I think was alright

I don't think a pop necessarily indicates a problem. All of my amps make some sort of noise (mostly a click or pop) when they are switched on and off. I guess that is one reason AMB made his soft start board, although the main reason may have been to eliminate DC offset problems with certain amps such as the Millet Hybrid.
It may be a difficult thing to diagnose without actually hearing it and most likely it is normal.
well I just got a package in the mail today with some OPA627bp op-amps in it
so I went to swapping the AD843's for opa627's!
the sound is not radically different, but I can tell there is some added detail to this amp. So far I've got about 6 hours on the new op-amps and I'm enjoying them very much. I think the fact that there wasn't a large difference could be that the AD843's are supposed to be smooth for AD op-amps... also and my source... x-fi xtreme music
I do have some extra opa627's though, so if someone needs some let me know
