I talked to ACC twice today. The first time I didn't give the guy much credit. After talking to PTC who told me that ACC is 4 doors down from them in the same building. So I'm thinking that behind those doors is an assembly line that makes the same converter with different labels on them. I called ACC who now in my mind has a bunch of credit and the guy told me that he also makes the TC's for B&M.PTC wanted almost $500 for a TC to suit my needs. ACC will make the converter I have now what I need for $60. Of course I have to ship it to them and pay shipping back.
