RAT vero verifying

[stokacik]

Hi all,
i made my first vero layout of RAT from schematic, would some kind member check it for me? I check it for hundred times, but i think i can miss something.
Dimensions of parts are not accurately because i dont know what parts I will order
Thanks in advance

Welcome to the forum.

Overall the layout is okay except for a few things:

1N4002 - polarity is backwards
100pF from row E to F in column A - should be 1000pF
1uF output from Q2 source - polarity is backwards

Also - the RAT schematic you are working from has a very small error that doesn't really matter unless you are a total purist. Coming off of the opamp pin 6, component order is 1k -> 4u7 not 4u7 -> 1k. Accurate RAT schematic is below.

That said, you should also point at the existence of 2 X D1 clipping diodes on veroboard, Gord..
