due to a wierd/tired arse ordering error, I got from cabintech 3 mn3007 and 2 mn3005's when I wanted to order 1 mn3k7 and 4mn3k5. now the 3k5 is gone from everybody remotely trustworthy except amplified parts and... it's only 3ish dollars more to get a v3205/3102 setup(4 chips) than what the man in AZ is asking for a single 3k5. can I swap on 1 of these boards ? how much alteration would it take like a regulator/zener swap?
