Thanks for the heads up on ssl mixed, going down that rabbit hole over there now too. So far I've got calls into everyone I can think of stateside and emails across the pond to recycled and funky junk.
I spent about 6 hours today trying to find the failure and finally realized it must be a 3 layer board. The +18 is shorting hard hard to the +11...pulled bypass caps, transistors, everything, even cut out as much of the burnt power section as was possible. Hopefully someone will have a spare because this thing is toast.
