Saw some like these on fleabay, They look very much like the Austin Armstrong/Monitec amps.

Thought as much I had a few myself not so long ago, I sold them to someone on SP but cant remember who, This is one of the smaller amps.


Nice sounding amps but did get a bit on the warm side when pushed.

I had a look through my photo's and this was the only one I could find (the other amp's I had all looked the same anyway)
They also did some 4 channel amp's that were quite useful.

Edit:
One thing, never try and run them @ 20hms/4ohm bridge they won't do it and will die quite quickly

seems to be quit clean inside , it did have some very back dust that i cleaned out , looks like it might have a 2x leaking  capacitors , it looks like some black goo has seeped though the glue on the caps nearest the fans , at first i thought some dust had just collected on the glue but it looks like a bit of a leak :/
the amp dose sound nice
 i had on channel drop out for a few seconds on power up , but seemed to be fine after , i gave the amp a half power test on Channel A and then on B , then a full power test for about an Hour ,

with out any issues ,

What age are these Austin Armstrong amps?
 
They look similar to some amps I was asked to help modify some years back as they had problems, mostly the 4 channel versions.
 
They claimed some affiliation to C audio at that time I believe. They were gutless.

The Austin Armstrong ones were circa '94 in various power and a 4 channel.
 
I think the guy was from Cambridge.
