is it present when the motor spins or stopped?
50 hz hum when using MC on Rega elicit Amp
I just assembled a new Ortofon Rondo red on my Rega Planar 3 TT.
It still need a run in but man...even now... what a mind blowing sound !!!!!
Apparently my 20 years old Rega Elicit kicks ass even in its MC input.
There is however a small issue with about 50hz hum I get.
The following facts might help troubleshooting:
1) I use an MC cartridge for the first time.
There were no such noise issues when I used an MM cartridge.
2) I hear the noise only when the interconnect of the Planar 3 is plugged in so one could think that it comes from the head... but.... could it be an MC phono stage issue that is revealed only when there is load on its input ?
3) Grounding is fine and I measured 1ohm from the RB300 bare metal to the end of the ground cable.
