Title: Ground lift?
Post by: Whaam68 on October 06, 2015, 10:11:52 AM

Hi
I built my quickie a while back and have used it on CD with no problems.  When hooking up to my rega turntable and phono stage there is a massive hum.  I don't get this on my other preamp which has a ground lift switch.  I'm planning to rewire the. rB300 to put a proper earth wire on it but in the meantime is it possible to add a ground lift switch and how would I do that?
Thanks
Mike

The earth is already lifted.

Try running a wire from the chassis of your phono preamp to the shell of an RCA jack on your Quickie.
