I can't answer all the questions but I use an Acom2000A. It's an autotuning
legal limit (+) amplifier, with extensive microprocessor control. It monitors
a slew of operating parameters and protects against any perceived problems. I
believe the problems being reported have to do with the amplifier sensing the
presence of exciter r.f. when it doesn't want to see any r.f. coming from the
exciter based on the keying loop handshake, but I might be wrong.
In its favor, its the quietest amp I've ever encountered, fast, will change
bands with a single dit, lots of headroom, etc etc.
There's an Acom reflector at http://groups.yahoo.com/group/acom-list if you
need more info.
