There is an article on the grounding of the Technics SL-1200 and you can find it here -
Internal Grounding » Technics 1200 Parts, Technics 1210 Parts, Technics Repair Turntable Repair, Mods Modifications, Pro Audio Parts, Accessories, and Repairs, Toronto, Ontario, Canada (technics1200s.com). It appears that the newer units are no longer internally grounded. Its not a safety issue, many electrical equipment such as plastic housing power drills are only 2-wire; from a ground safety - they are intrinsically safe and the reputable ones are UL approved. But even if the motor was grounded, unless the metal tonearm is somehow connected, grounding the motor is not going to help.
Can Static Destroy Electronics?
The Story —
I had been listening to records all night, no issues. I put on an album by Junip, brushed the album with my anti static brush, and went to lift the tone arm by the tone arm lift when I heard a loud static pop. Volume was about 30% up. After which, there is no sound in my right channel.
I think the issue is at the output of the phono preamp, because:
- When I switch the L and R input cables at the phono preamp, the left speaker still plays (the R signal stuff), and the right speaker stays silent (meaning the right input must be working)
- When I switch the L and R phono preamp output cables, the right speaker plays the L signal, and the left speaker is silent (meaning the right channel all the way up the chain from the speaker through the signal is working)
So...did static electricity blow my right phono output?
