Those are not heatshrink, they are cotton that was treated with some sort of epoxy. They were on the original to begin with. I am mostly glad the monster 100uf that is easily three times the size of the original, actually fits.
Anyone who has listened to a Vinnie modded one knows that these amplifiers are quiet some amazing for what they are, and for the price, even with the price tag for mod, they are worth it. To bad Vinnie is out of the game for them! Although to be honest I would like to just listen to a model 30, I bet it kicks serious ass.
