IMO ignore everything except its amps output. If it walks like a duck... etc. Anyway you got the original 60 from Randy and sending it back to Florida didn't work out. So now you want him to look at that "75" himself (he has a shop) and pay the shipping and try and figure it all out, since the other guy didn't get around to it for whatever reason. Info Errin on it too. He doesn't like cranks but is reasonable with reasonable people, and he has some sway with Randy AFAIK.
So IMO now this isn't a tech problem, it is a customer problem you can sort out with those guys.
