Cheers Colin, always interested in circuits. Its a good way to learn different ways of doing things.

Oh, and thats some highly optimistic prices for the upgrade components. Looks like he rolled a couple of dice to make those prices up.

Hi Colin,

I am actually quite interested in the pre-amp cct. It's just that I'm in that place of 'so much to do, so little time' at the moment!

Cheers...

Yep the prices where a tad on the extreme side more so back then 1987 when this amp was published in EE I think back then the leading Cap was the wonder Caps oh and the infinicap plus the vishay VSRJs most of the files I have for this complete pre/power amp are to large the post or email but
if anyone would like the full build details I would be happy to make up a cd/dvd or two and send out for free but UK only ???? limited
