AV400

katiyar · 18th August 2011, 05:48 PM

I intend to construct two channels of of the popular AV400 MOSFET amplifier. I have redesigned the PCB which was previously posted by some viewer of DIY audio site. This PCB accommodates large reservoir capacitors. The original design is not mine. Can some one debug the PCB from the schematic.

Sorry the PCB image file was left inadvertantly.

Has anyone assembled AV400 Amplifier. If yes, what is the performance, distortion level etc.

That's why I use net lists. If the schematic is correct, the PCB connections will be too. BTW, where is the schematic to compare to?

Mistakes were found in previous layout which have been corrected. Interested readers may check the layout with AV400 Schematic.

PCB is very good. But it should be better if made with fiberglass board instead of phenolite.
