I have hooked the amp up on one of the mic inputs to the computer cd-rom unit as source nad i must say it sounds really good.

Heres some pics of the amp:

Goodness, this amplifier was made before safety was invented!

Seriously, get rid of those selenium HT rectifiers. When they expire, they have a nasty habit of taking the mains transformer with them. Measure the HT before removing them, then replace them with silicon diodes (1N4007), and if necessary, add a little series resistance between the transformer and the rectifier to restore the correct HT voltage.
