Three TDA7293 in modular schematics with PCB design and gerbers

[pbilous]

Just for fun made gerbers for three TDA7293 in parallel (modular) design based on this old website http://buildaudioamps.com/tda7293/

Gain is set to 26dB

Hi
Is this tested? How is the clarity of the sound?

I ended up going with different schematics using only two tda7293 in parallel

If you might be interested in simple composite with 70dbNFB@20khz instead of 24db, that is 200 times more error correction. Here is a working circuit, you can parallel to get 65W 8 ohm 120W 4 ohm.
It has start up plop issue.
