I have seen these amps and they look very nice. Good shape except one small screen on the rear where the bias screws are. Not exactly like the pic but close. Look nicer in person and they have cages.
They have a stamp that reads "made in the UK" so information is very limited. How these Brit made monoblocks ended up in the middle of nowhere is beyond me. I did find these specs on another thread.

I don't want to discuss a price in this forum though. But without any reviews to read or anyone with personal experience to pass on, I don't know if the price is reasonable. I would like to get in low so I don't lose my shirt should it not end well.
They look just like these, including the bias meter, except for round badges on the front. Cages are off in this fellows pic.
