gounding RCA jacks
« on: 24 Sep 2007, 08:23 pm »
Hi,

I've read through as much as I can find on grounding for the bugle & PS here.

One question though... should the RCA jacks be grounded to the chassis or isolated from it?

I'm using these from digikey:

My intent is to run earth ground to the chassis and the bugle ground (the one near the inputs) to the chassis. Turntable ground will run to the chassis also. Should these three physically share the same post, or do they just have to get to the chassis?

Thanks a lot,

-Keith

It is usually best to isolate jacks from chassis.  Chassis ground can come from power cord.  Then it connects to BUGLE at one spot, usually at the inputs.

They do not all need to be same post.

I have some questions along these same lines. I have my Bugle board in one Hammond aluminum case, and the P/S in another, identical case, with an IEC inlet for the power cord. Should I connect the ground to just the case, or to the P/S board ground eyelet as well? And, depending on how I do that, how would I connect the ground to my ground lug screw on the Bugle case, which I must have in order to connect the ground wire from my tonearm. Should I isolate the ground lug from the chassis, or ground it to the chassis? Or is it a matter of 'try it and see'? (Clear as mud? :duh:)

Yes, the board should be grounded.  Do it in one spot.  The easy way is to make the ground lug used for TT connect to the chassis.  Use that point to tie the ac line earth, and use it to wire up the PCB ground.
