Valves and PC's

[AJB2K3]

Well i'll soon be imbarking on my biggest pc challange to date.
A pc that will have vale amp for the audio output.

A little information.
A while ago i saw this which inspired the design

I had an idea on using 2 to give the 4 front speakers a classic sound and the pc a old fasion look but i had a thought.
Is there a good circuit for valve amps thats easy/cheep/realible to build?
i would also like to be able to switch in/out the valves for the audio but whats the best method for switching.
If this all sounds wierd im sorry because i know absolutly nothing about valve amps.

P.S. Will they cause interference that will harm the rest of the pc?

Hi AJB2K3,

AOpen doesn’t seem to have any interference problems with tubes in a PC!

Go for it, and good luck!

IM trying to work out how to get sponser ship because of the amount of cm stuff im using.
Just to intrigue readers this is how it goes.

creative X-FI > 2X above units monitoring single channels + another unit monitoring the vu of the other channels (bass channel still to be worked out.)
I hope to make a sweet (frankinstien era) sounding pc case.
