You're right that Alpha worked with Acom on production of the 91b. It's
also true that the relationship between Alpha and Acom floundered. I 'm
pretty sure there will be alternative truths concerning the detail of what
went wrong in that relationship.
I can't speak from experience with the Acom 2000A but I can on the Acom
1000, which is one of the best made amps I've ever had the pleasure of
using. The quality of construction is a joy to behold. Mine was one of the
first Acom 1000 amps and is about 4.5 years old now. It's never missed a
beat and frequently does 48 hours straight in contests.
>From the contact I have had with the Acom folks I would say they know
exactly what they are doing. They are a very professional bunch of folks.
Usual caveat: I have no financial or other interest in Acom other than as a
very satisfied owner of an Acom 1000 and potential purchaser of an Acom
2000A.
