Thanks for PCB, but i prefer the already tested one in practice
to Zen Mod:

The table below gives rough guidelines of how wide to make a trace to handle the current:

0.010" (0.254mm) 0.3 Amps
0.015" (0.381mm) 0.4 Amps
0.020" (0.508mm) 0.7 Amps
0.025" (0.635) 1.0 Amps
0.050" (1.27mm) 2.0 Amps
0.100" (2.54mm) 4.0 Amps
0.150" (3.809mm) 6.0 Amps

0.236" (6mm) out of range

And that is without soldering (covering) traces with solder.

in short - gate trace can be narrow

both drain and source traces must be at least 6mm wide
maybe this is better....

Hi Mindutis.

I didn't see your post before my last one.... thanks for the guideline.

but anyway... no trace thinner than 0.050" now. The amp sucks 2 amps @ max power. so this must be fine..

or is there another failure in the layout

Boards Ordered!!!!1!1!
they are double-sided..

& yes, the amps really are "handy to have around the house"
1001 uses.. (OK at least 10)
Also make great gifts for that special niece or nephew..
