No cap replacement. No leaks or bulge's though. I just sent them in to get checked out fully since I didn't have any way to do it at the time.

You could actually buy a V2 upgrade kit from PG. I think I've seen one on here or Ebay in the past year.

Nothing shady about those amps as I'm the seller. I'm over on DIYMA under the same username. I've been on here for a few months but just lurking.
