One more reply (to myself). I'm looking for some assistance now, I think.
I checked resistance on the tab of Q6 and get 1k ohm.
Resistance at pin 1 of U1 is 3.13k ohm.
Both are supposed to be over 500 ohm, according to p. 58 of the most
current manual.
D7 checks out at .742 one way and .538 the other way, so I think it's
alright (forgive my lack of technical jargon; I'm tired).
I think the only thing I may need to repair is the trace between RP5 and U8.
So, the question of the evening is...
Anyone have any idea why this happened? Was it just the fact that more
current was flowing through than necessary and my DC wasn't fused at 1A
or so? Everything else seems to be in order.
I just don't want worse damage next time, or to have to do this repair
more than once. Thanks for your help, all.
Off to bed!
