I picked up one of these a few months back, the smaller one with the 2 ERF7530's in it at a local flea market. It was brand new never used once. First thing I did was to open it up and check everything right down to the smallest detail. AB1 biased, good solder joints and all top of the line components. I put it back together and ran it with my 2950DX and so far no complaints here. Solid 200+ watts on SSB and really good reports. I've ran it a bit over the specs I found on it and it's taken it all with no downfalls. Currently use it in the wifes car with a Wilson 5000 and have made numerous overseas contacts to Europe and Australia. I will say the heat sink they used is a different type set-up than what you find in most amps, It's well machined and inside the amp with ducting for the fan to pull air in and around it and past the finals. I've ran it really hard a few times and it does not get hot. IMO it better quality than a Palomar amp.

gee, I jus dunno 'bout that
Solid-state amplifiers cannot be class "AB1" or class "AB2". A bipolar transistor amp cannot be a sub 1 or sub 2 class because they do not have grids to have or not have grid current. Solid-state amplifiers have bases or gates, and a bipolar transistor always has base current.
