Also all of the SIMMs I have here are single sided.

I read somewhere that CHIP RAM simm MUST be doublesided, but maybe that was wrong info? I have Rev B also and this has stock doublesided simm as Chip mem, others are singlesided.

I would suggest to try other PSU before attempting repairs. You can install ATX PSU with adapter for Amiga, then you'll know better..
