Need a little help with Original Parasound JC-1 amp(s)

So I have pair on demo from a local shop and it appears that they have had parts replaced throughout the years. In the picture I’m looking for the missing heat sink on the input mosfet and I also wonder if anyone notices anything else out of sorts? Any help would be great!

Paarasound made some improvements and upgrades over the years. How do they sound?

Russ69,

They sound pretty good, but the rebuilt amp runs much hotter than the older non-rebuilt amp that has the missing heat sink. When I first got these amps they had mismatched parts then I asked the dealer to match them up and so far they look a little better from a parts perspective but I don’t know enough to notice right/wrong on the internals. I’m having a friend/tech coming over tomorrow to check the bias and DC offset as well.
