hi andrew try tekko's pcb desing . because mine works but i still have small issues with rf noise maybe because i did not use etched boards, the fets were mounted using the pins . but still would love to bridge the monster if there was a scheme. nice design guys steve

well,now ceck clearance on component near -vc and +vc (i see small capacitors not have right clearance at sx of pcb).
now is necessary completed first modify.(simple operation) connession at input toroide change layer with bottom and create vertical gnd with blue layer (this gnd close loop on top ) actually loop is large,(from operational up to toroidal filter). is better move 3-4mm at dx toroide.
After this, you can force both layer for output and GND output.

Nice board! If you could get it to work then I have no doubt that the amp works well..
I design my board as a single layered and I will create myself it by ironing.. so the routing paths have to be that way.. and the spaces.. It is easy to design duel layer board but in here, there is no place to make it.. even it is, it will be very expensive so I better do it this way.. all cheep and 100% DIY.. LOL but Im thinking the best way I can rout it yet thanks to advices.

regards,
Lycanlk
