...have crumbled into dust." Really? I've never seen that happen to a circuit board, and I'm a restorer of vintage electronic items. The only exception would be due to long term heat exposure from e.g. a tube socket. I wonder if Revox got ahold of a bad batch of pcb material? Even the old paper phenolic stuff in cheap '50s transistor radios still holds up reasonably well. I recall that later versions of the A77 were using the green colored glass epoxy boards. Those should hold up very well. I'm sure replacements boards would be available, as a lot of these decks have been parted out.
