is that inside a working computer, or just an empty computer case? looks cool!

Looks nice.

You could think of putting a chromed cage around them thogh, they look a little "vulnerable" like that!

In the tradition of case modding, you must now add cold cathode fluorescent tubes and Blue LEDs to pulse in sync with the sound. :)

And, erm, are the tubes overclocked? :D

Uhm Shifty, generally you *don't* want parasitic oscillations in your amps :D

And yes it's the computer he's using right now, er, then...(I helped him thru a lot on ICQ so I should know :o :) )

Theres no real shielding.. well the wires from the RCA jacks up to the first coupling caps are shielded, but everything else is normal.


Heres the schematic. I suppose I should add some cathode bypasses sometime, but I'm awful lazy, and it sounds good as-is..

I'm not sure on the value of the chokes.. they're pulls from old TV's.

li_gangyi 24th June 2003 06:19 AM

Hmmm...the ch0kes are more than 1H?? New TVs now seldom have big chokes...you might want to get some screening on it...though I dun think they will be a big difference in the sound..it will help your PC alot though...
