Triplanar RCA out to Balanced out for MP-1

Nandric, Obviously you need to be comfortable with whatever you do, but I guarantee the hum associated with poor grounding of the tonearm will not hurt your speakers. It's 100Hz or below in frequency; even the midrange is not involved. Moreover, it is low level at normal listening levels, e.g., I was able to listen to and enjoy the RS-A1, hum and all, before I fixed the problem. Congratulations on your expensive speakers, however, and I do understand your desire to avoid damaging them. My Triplanar is about 15 years old, but Herb Papier, the original inventor and manufacturer, upgraded it to VII status as one of his last acts prior to selling the company to Tri Mai. In fact, Tri was visiting Herb to learn the art, when Herb did the last upgrade. I am not aware that there was any difference in grounding the shield or not grounding it at the tonearm side among various versions of the Triplanar. But you may be correct in that inference. Anyway, this is a simple fix.

BTW, My assumption that your hum will be 100hz or below is based on my guess that you live somewhere that has 50 Hz mains frequency. The hum will be at 100 Hz or at 50 Hz, depending upon the rectification of your amplifier. If you live with 60 Hz mains, then hum is at 60Hz or 120Hz.

Dear Lewn, You are right,as usual,but this time on logical
ground: if the assumptions are 'wrong' then no deduction how ingenieus made will do. I live in the Netherlands with 50 Hz mains frequency. So your primary assumption was right.BTW are you implying that I will,then,blow up 'only'
my bass-speakers but stay alive because there is no danger
from my beryllium -units? (kidding).
Regards,

Nandric, you speakers are simply in no danger regardless of what you do with the arm. It all has to do with what you do with the volume control :)
