I will post a pic later but I'm glad it worked first time I fired it up,not a complicated build but it was a self etched board using the Tonepad project(thanks Francisco) and I had my doubts cause my hands shake a little nowadays and I was afraid I had joined pads that were not supposed to touch.
All went well I have to box it now.
Used 2N5088 instead of 2N3904 I had a few 3080s so it was asking to be built.
A lot of gain and sustain.DID not have a rev log for the sustain pot but log seems to work fine.

All parts from my junk bin and only had to use one ceramic cap cause had nothing else remotely near 0.05.
It's only noisy if you crank the sustain to 10.

How do I set up the trimpot?
Thanks
Aharon
Ok found this from Analog man

The trimpot on the Tonepad layout might not be related to Analog Man's CompRossor circuit. I can look at the Tonepad schematic and see what's going on, but I'm sure someone far smarter than me will chime in at some point.

Ha! Right on the Tonepad page for the Ross Compressor:
"Q. How to set the trimpot?
A. Set the trimpot in the middle, slowly turn it to both sides while letting single notes ring. Leave it in a position where the decay doesn't sound gated."
There's your answer.
Roger
Thanks Rodgre but as we speak I'm building another one. As I was boxing it I forgot to drill the holes for the standoffs and I was drilling the bit caught on and spun the pcb and al wires like a party croaker and destroyed my Ross, serves me right for saying I wasn't' etching anymore pcbs
Hope the next one works too, and will drill all holes before. :icon_cry: :icon_redface:

New one is done and works fine, less noise than the previous one, couple of differences :D1 I used a 1n4001 this time cause I think that's the one that prevents wrong polarity ,no ceramics and all resistors 1% .Tight layout but its doable you just need a soldering iron with a sharp tip.
