I did one over the summer, its a nice box to work on.
Sadly, unlike the 8200 etc, you need to get the entire central chassis out to get behind it to change the belts. I was going to change my pinch roller as well, but it was in remarkably good condition, and I couldn't find one that I was sure would be a good replacement. I found the record bar on mine was a nightmare to clean (it was full of fluff) which took a lot of treatments with contact cleaner to get it out.
Strangely, two belts remained as belts, but the drive belt had turned to that strange black goo which truly gets everywhere, and took hours to remove from the 'brass' drive spindle.
I had hoped the 8080 performance wise, would be pretty close to my 8200, but I find the performance to be lesser. Also, the 8200 line in works perfectly, but I think the 8080 needs a pre-amp in line to drive well through there.
In my opinion, the 8080 is a pretty box and I did find it a decent box to work on. Good luck with it.
