You should be able to find the pcb revisions by looking at the main PCB designators on each of the boards. Mine had a number of revision numbers listed with one marked white so i can only assume thats the current revision when my board was made.

I think the majority of schematic changes were with the power amp section, changing the grid stoppers from 220k to 5k6 for instance. There are also a number of component designator changes as my power amp pcb doesnt match my schematics unfortunalty!

I took a load of photos inside the amp prior to any mods, just in case i had problems rebuilding the amp, ill check them later to find out my pcb revisions.

Once again, thanks for the endorsement!
