Loud pop and scratching noise when i turn on my piano? Please Help

[RhodesTastic]

Ok so when i turn on my Rhodes i hear a very loud pop (as well when i turn it off) and there is like a weird clicking noise and a hum. i know its not the amp because i unplugged the 5 pin cable and then it didn't pop and there was no scratching noise or clicking it was fine. but when i plug in the piano to the amp with the 5 pin cable and turn it on i get that loud pop and scratching noise. idk if the 5 pin female connector on the amp is out or if its my pre amp where the male 5 pic connector is

Does the weird clicking noise speed up and slow down when you turn the speed knob on vibrato?

[RhodesTastic]

yes it does!

I came across this once before a while back, again let me check a preamp over the weekend and get back

Any success? I found that this issue doesnt happen every time i turn on my rhodes. but it did today. and i could also hear a local radio station threw the speakers as well.

Unfortunately no and I forget the solution off-hand, did you say you believed a ground point was missing?

yeah. iv been trying to figure out what the deal is. im going to bring it in to the studio tonight and run it threw a tube pre amp. to see if its the pre amp. then im gunna run it threw the Bricasti reverb unit. its probably going to sound Amazing lol
