First Layout (vero) - Ruby Amp (validation needed)

Here's the schematic:

And here is my layout:

I've been afraid of drawing layouts for some time, so i choosed a simple circuit to start. But since i'm a begginer i do not feel certain that everything is ok with this one.

I know i could tighten the layout, but for know i just want to know if i made some mistake or not. And i would prefer to know that before building the circuit

thanks

No one?

Check your JFET pinout: I think the MPF201 is DSG not DGS from top to bottom when viewed from above with flat side facing left. You could flip the JFET 180 degrees and swap over all connections and cuts on row b and c. I'll check the rest of the layout when I can see it on a bigger screen (not phone).

Other than the mpf102 pinout, it looks good. You could eliminate the link next to the 220u by taking the 47n directly to the bottom row. You also may want to scoot that 47n, and possibly the 10r, over to columns g and h. 220u caps tend to be fairly big. YMMV.

Thankyou for your help and sugestions.
Tomorrow i will update the layout and start to build.

Next endeavour is designing and etching a pcb.
