I have recently refurbished an Oracle Delphi Mk 1 and set it up with a Fidelity Research tonearm.
All fine and dandy and sounding pretty good.
The noise floor is really low and there is no discernible hum.
But a strange thing happens when I put on a record on the spindle or take it off after a spin.
I get loud popping/crackling sound through the speakers - sort of like loud static electricity pops. If I touch the metal spindle on the TT, I get similar pops. Interestingly, once I've touched it, there's no further pops after that. And after a few record changes it does not seem to occur at all. But every time I start the deck after a period of no use, the pop happens again.
I am guessing its something to do with static electricity? Or something worse?
The tonearm cable is well grounded and there is no hum through it at all. There's no pops or hum when I touch any part of the tonearm either. So, it seems to be something to do with the body/spindle of the turntable itself.
Any thoughts? Do I need to have a separate ground loop from the body of the turntable?
