"Are those computers?"
"No."
"Servers?"
"Nope."
Instead these two mono block amplifiers are somewhat experimental build with active cooling, using 2 pcs each = 4 pcs total of Dell server CPU coolers and each of them contains one Noctua 140mm fan, so 4 Noctuas also for stereo pair. Power output is about 55w@8ohm which is very good result with pure class-A amplifier. Heat dissipation is something like +200w per amp, over 400watts total.
They sounds really powerful, you couldn't believe there's "only" 55 watts of power!
I made variation with black and aluminium sides, prefer black maybe. Top cover is 6mm slightly tinted glass.
Each mono block contains;
- 545va 2x30sec trafo's, making almost 40vdc rails.
- Inrush current limiter.
- Kemet 15 000uF 63v caps, making 150 000uF per channel.
- SMPS for fans, they run at 12vdc and are quiet enough.
- 2x noctua 140mm fans.
Thanks DIYA, Akkeli for metal work and everyone else involved :)
