It is Quasi's NMOS 200 amp, his website is here:
http://www.adam.com.au/cgpap/QuasiWeb/index.htm

It has been built by a few forum members who report it works very well. It is a class AB able to deliver around 100W into 8 ohms.

if Quasi should change the name of his PDF folder
from /pdf's/
to /pdf/
then his links would not be broken when posted in forum.
Forum software does not like single quotes in posted links: [ ' ]
Single quotes have special issues in PHP+MySQL Database scripts.
This would of course work just fine:

Both links are working for me, the first directly and the second after about ten seconds of own efforts (strip last dir in path, then follow the redirection)
