I have two Mk III and Mk IV combos that I'm in the process of converting to heads. Does anyone know if the reverb tank cover is available separately anywhere?
I purchased one last year from Mesa for my Mk III. It's not in the Shop on their website, but you can get it by emailing or perhaps calling. Here's the part information:
221675 (Chassis Cover Reverb Tank 16-3/4X4-1/4)
