Hi,
I'm curious if it would be possible to swap a mk2 display board out for a mk2a display board.

I've got a few empegs here which are in different stages of disrepair, I'm trying to fix my buddies empeg which got crushed under a pile of heavy amps, with a mk2 unit I purchased off of ebay. When removing the mk2's knob (it had to be glued), I managed to pull half the encoder apart and maybe cracked my display nipple. I still can't get the knob off of the shaft after removing the shaft from the empeg.

So, I'd like to get at least one empeg somewhat usable while I wait for some extra encoders. Can I swap out the mk2 display board and install the mk2a version into the mk2? Or will I run the risk of breaking something else?
