We played it right out of the box, typical trough switch adjustments but the rubbers were dead and needed to be replaced.
I took off plastics and changed rubbers cleaned a few oxidized sockets and wax.
Drops were sticky but broke in playing it, they were real snappy after I took it to PPE.
Also after assembly the on/off switch was faulty, the rivet for the lug was on the edge instead of the hole in the middle and the wire fell off.
I had one on the shelf and just changed it out.
A few of the inserts are cupped, I just left it original, I don't want to ship the PF.
I also tuned the spinner and lubed it with Eezox.
You will just have to see, even though it is new it still has sat in the box now for 33 years.
It may need a Big Blue, I bought one from The Real Bob Roberts but haven't needed it so far.
So far it is holding up great with no signs of wear.
Personally I wouldn't clear it just keep it waxed and keep it original.
