The error message relates to the polygons used in Eagle to create connections for the positive and negative supply rails and for ground. Their absence renders the rest of the board files useless. Time to learn a bit about Eagle, I suppose!
Ah, missed that bit. Cheers. Presume this is how it connects on the amp board. (using the same wiring colours as before. Red to J3, Black to J4 and Green to J6)
I bought some via ALIexpress a few years ago, but they don't seem to be offered any more. I ended up using some Eagle files from the Bulgarian site mentioned to get new PCBs made (but not the original format boards).
This is quad405. and it is quad405 MK1.
The old version of quad405 is not 405-2 or above.
Because versions above 606 are not of this structure at all.
You should change your title.

If anyone wnats to try the Bulgarian PCB, here are the necessary PCB files. I take NO responsibility for their accuracy and no liability for their use!
