hi bud

good work, this is a brilliant design. I just have 1 question can this amp run in bridged mode to 2 channels and what would the output be?

Thanks

it is just amplifier board you will need phaze inverter. it will 2 channel mode @ 200w/4 ohms

Ahoj the origanl schematic uses 2 pairs of output transistors, why you use only 1 pair of them? Can you make pcb for 2 pairs? thanks for answer and sorry for my poor english

Very nice design and build! It looks great, solid, well laid-out, and functional.

Question: How did you design the PCB? It looks too nicely done to be hand-drawn (of if you did do it by hand, you're amazing!) and looks to be CAD of some sort. I'd love to know how you did it!

Thanks for sharing your work!
