Despite being a valve amp, theres no way it can sound decent whilst
being run inside the PC casing. AND you lose several PCI slots, and
degrade cooling (valves run hot!) in the machine...


Why not make a compromise, and build one of my Quad405-2a amplifiers?

I've  re-engineered the Quad405 design for:
Reduced noise
Better current characteristics
More modern components

Whilst at the same time, preserving the things that make it great.

I've not finalised the design - I need to build one first to test - but
when I do, I will publish it under the GPL.

Its a mono amp, so you'll need 2 of them, and a powersupply. I recon
that you could piece one together for about 150-200ukp.

You'd need a pre-amp of some sort too. Thats my next project ;-)

How about it.

If you could avoid mon, wed, and fri, 9-5, It'd help, but really I can
go almost ANY time. over to you...
