finally finished computer amp!

Colt45 · 22nd June 2003, 01:31 AM

Finally finished this thing. 6V6 SE outputs, E82CC (SQ 'AU7) gain.

5Y3 CLCLC power supply.

about 4mV hum.

ideas / questions / etc?

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?

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

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

)

i assume its shielded inside somehow?

li_gangyi · 23rd June 2003, 04:34 PM

can we se the schematic?? thanks

karma · 23rd June 2003, 10:30 PM

ok now i can say i have seen everything

nice work

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, 05:19 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...
