Slipknot-My Scout was possessed from the first day. Thankfully my dealer, Larry at Hollywood Sound, is standing behind it. (Shameless plug, but he is the best)
Anyway, it hummed when I touched tonearm. Evidently was shipped lacking a ground. Dealer grounded table.
It recently developed a hum when the ground wire is attached to pre, but is quiet when no ground wire is attached to pre. This is the opposite of what we expect, eh? Also the hum increases in volume when phono wires are touched.
Dealer has checked and checked, and now suspects Dynavector may be at fault. We are awaiting another cartridge.
Sbank- I irregularly use the last Stykus clkeaner and its companion stylast stylus treatment on the Dynavector, but did not have it when I was operating with the Ortofon.
So is there observable indicia of stylus funk?
