Anyone own an NRG Control PA-1 Preamp or A401M monoblocks?

The amps were really good at the time. Dont know how they would stack up against S.S. of today. It seems to me that the amps were a bit unstable and had problems. I dont know anything about their preamp.

I remember reading that the company that made them was actually in the medical equipment business primarily. I did lust after them at the time. I've seen a couple of the amps for sale over the years.

Well I actually have a pair of the A401m mono’s and just bought the matching pre. All faulty, amps will be going to a tech soon, for the pre no schematics exist and Denton Clarke said he doesn’t have any diagrams for them so would like to hear from someone who has one to confirm a few part numbers of transistors missing from mine. I’ve had the monoblocks for 5 years waiting to get round to repairing them and would love to know if they sound as good as their size and price suggested. I have a scan of the brochure which shows they they’re rated to 12000w per channel, no that isn’t a typo, 12k watts each at 1 ohm capable of 195a of current. No slouches...
