I've couple more questions im afraid ;-)

So looking at the layout as it is in the manual on page 20. 

Which pin on jp7 is lfo1 out and which is inverter input?

Which pin on jp8 is inverter output and which is to lfo1 jack?

Can i take the ground for the sockets from the lower pin of jp4? (my meter says its grounded but i'd like to be sure)

Finally, the jacks for my blind panel aren't the cliff type, so when grounding them im going to inevitably ground the whole chassis, is this ok or are there any potential caveats?

I know its a few questions, sorry, still waiting on my power supply so i'm not able to test it yet.
