Not even sure if overvoltage has caused the problem.
PSU is a funny design alright, there is a big old transformer that outputs 37 VAC form a range of mains voltages (110-240V) and feeds a switch mode power supply.
I can't see any obvious damage, desoldered rectifier and chopper transistor, they are OK. Desoldered all caps and they test good as well. There still is a short between power and ground at DC input to the PSU (after the rectifier). Might be the voltage regulator IC, this crazy 18pin IC (EC-A063) for which I can't find any info.
Could pick up a replacement for $15 but shipping is another $25...not really worth it...not desperate enough yet
