This is my layout and no extra componets added.
resize to 82.8x34.4mm in your printer setup.

Juma, very nice board design . Visually it expresses the simplicity of the circuit well, and as you mentioned, it seems to have all the requirements of those of us commenting, and that's hard to do

Maybe someone will do a board run, but it is even better that lots of people seem to be making their own boards!

I wish I had a lot to contribute, but this far in my DIY career I am just a copy cat

Thanks to Mr Pass and all the rest of you making this easy for the rest of us. I really appreciate it. (course I still have to build it. Probably in July)

Moreover, the gate resistor seems to be 150 ohms in lieu of 47 ohms indicated in the published schematics. (Assuming that the left hand resistor close to the gate is R14)

A special tweaking or........???

Who know the answer,please ?
