Default "Hybrid A-1000" - Very Old MOSFET amp

I am totally out of my depth here and need advice from some sound gurus who have been around for a long time!

With the hope of building my own PA system on a budget, I recently bought a very old amplifier with no manual and I have not been able to find out anything about it online - I can't even find the manufacturer's contact details! I want to build my own speakers to use with it, but before I buy any components I have to be sure that I've got the load matching worked out properly. How can I figure out the output specifications of this amp?

The amp weighs a ton and looks like it was made in the 1980's. On the front it says "HYBRID A-1000 MOSFET Amplification", it has left and right channel level control knobs which each have an indicator showing a 500W maximum. On the back it says made by Hybrid Electronics, the model number is A-1000, the serial number is 169312, and it has a 10 Amp fuse rating.

Can anyone help me please?

I have confirmed that the amp was made in South Africa in the 80's and the manufacturer no longer exists... Also, it is definitely 500w per channel... but at what Ohm - that is the question!?

Im Ex SAfrican so maybe I can give you some clue where to start the search. Contact these two companies and try to get the info from them. They sold the range in SA, probably still do. I very much doubt these amps are manufactured in SA though, probably imported.
