Triplanar RCA out to Balanced out for MP-1

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 :)
