Just a final comment on the droop seen on many 7082 and 7045 arms.
The only way I believe you will ever see one of these with zero droop is from a nos example that has lived in its sealed box all of its life.
Many reasons for the droop to exist on used examples.
Not really, the NOS are normally very expensive compared to gently used samples, just like everything in audio. I've seen only a few NOS samples in 5 years or so, i bought one of them, it was 7045, sold it when i bought long 7082 (used). My 7082 does not have any problem with rubber grommet, but it's original, everything is clean like new.
Regarding the used 7045 only 1 out of 3 wasn't perfect. So it's possible to find a perfect used sample, nice and clean.
Another problem is oil in armlift, but the whole armlift can be replaced with new jelco armlift.
The problem is that most people selling junk on ebay, i prefer to buy everything from a perfectionists like myself.
