Also, I found cracks on the plastic cams on the shaft. The cams are still

Yes, both of my 7A29s are like that. On one of them a couple of cams had rotated so the attenuator settings no longer made sense. I added a fillet of epoxy at each side of each cam (I used Loctite 3430 because it's what I have in the lab, but other would probably do fine) to support the cams on the shaft. Time will tell whether it works long-term, but they've been OK for a couple of years now.
