Pavel Dudek's (Upupa Epops) amplifiers II

223 with heatsink...

Another project of last years is CLC1 ( CompromiseLessCrossover ), which is universal analog crossover, 2-4 way, in modular conception, 24 dB/oct in state variable principle, but it is not still ready...

Partially off-set...

Detail of balanced outputs amps...

And PS for this equipment ( both - CLC1 and PS - are in full dual mono conception.... ).

Another look...

And at the last some pics from scope : 223 at clipping ( cca 100 W into four, 1 kHz....)

Dtto, 10 kHz....

Square wawe, 100 W into four, 10 kHz...

No P-A, yet not...I hope they are precise, which is your " standard "...

Oh no, P-A, it is misunderstanding - my words was about your yellow pcb...

Case

Case is standard 3U one from Modushop, but my some parts are custom made from brushed stainless steel, cut by laser. Rear panel is overwrite by laser and coated against fingerprints...
Every my amp ( and crossover too ) you can remote from preamp. By multiamping they are switch on in turn ( for better inrush distribution ). Remote chain is galvanic separated ( no ground loop )....
Real panel...

And some enjoy for Spirtos...

I like sound of well made mosfet amps and this love lasts from the time, when I heard first EBs Hafler 280...
I had build many types of mosfet amps ( Borbelly and Hawksford/Cordell ones with error correction - they are my perfection )...
Type at pics is my basic one ( designed in 96 ). Look at precize work of my friend Filip Honzarek...

Bottom side...

All is gold-coated, including power mosfets...
