Intentional to Fit Dynaco Mark II Mark III Amps?
I have Dynaco Mark II chassis here (the later ones, same pcb cutout and mounting holes as the Mark III's) and for the heck of it, tried the "mistake" driver pcb on for size. It matches the mounting holes perfectly.
I show it bottom-side-up as that would be the top side -- the side with the tube socket on it. If I mount it under the chassis with 3/8" spacers, the bias pots will clear and I can still easily get a screwdriver from the top to adjust them.
Are the "final" boards also the same size as the "mistake" boards?

Remember to mount the tube socket on the non printed side..The other components can go on either side.

The new boards are slightly bigger - 4" x 4", and the mounting holes are on 3.5" centers. Pretty close, but different.
