Very well....do you find it useful to use the five-position damper on the back of the counterweight?
It was a mess to figure out how to assemble all the parts of the counterweight mechanism correctly when i bought my first beaten sample of GST-801. This counterweight is indeed a bit strange, there are rubber washers and a thin metal washer too. Luckily with my NOS sample everything was assembled correctly on the factory.
Are the counterweights of your Epa 100 still sealed or leaking silicon oil?
I have already had an Epa 100 overhauled with the counterweight drawing small traces of silicone oil on the outside.
Owned two samples of the EPA-100 and one EPA-100 mkII i have never seen any leakage from the counterweight. The only problem i have had with my first EPA-100 (after complete rewire with VdH silver cable) was a bad grounding of the arm, i think a person who did s job was not qualified or not tested it, he did some mistakes with a ground wire. The arm itself wasn’t perfectly grounded. So with my next samples i’m pretty much ignored the idea of rewiring, when everything is just perfect i do not want to upgrade anything (my rule number one now).
