Static or ground issue with PS Audio GCPH?


Hi all, having an issue I can’t seem to resolve for some time now. I have a VPI scout jr, ps audio GCPH phono pre running to a Marantz sr5011. I also have an oppo blu ray and Nak cassette deck connected to as well as a PS4.

i don’t have any problems with the digital equipment.
When using the TT I have always had a decent amount of noise come through the speaker, a hissing/buzzing in the tweeter. I tried so many different grounding options but could never resolve it and just assumed it was dirty power and/or static. I get a lot of static from the TT, use a zerostat on my record prior to playing them but if I seem to touch the platter while taking the record off I get a shock. If there is a good amount of static when removing the record from the platter the GCPH reboots (I assume this is some type of protection because it’s getting a charge). The GCPH was already fried once and repaired I don’t want it to happen again. The kicker is it fried when trying to connect a ground wire from the GCPH to the TT so not sure if that was really the issue or not.

when I have my Vincent Pho-8 pre connected instead of the GCPH I get some of the same noise but it has never shut off on me.

i got a small shock or two from the Nak today as well. Trying a humidifier in the room for a bit to see what happens.

Any thoughts/suggestions??? Please help!!

Was really hoping someone would dive in cuz you got a lot going on here. Static is always a problem yours is just worse than usual. For immediate relief get Static Guard anti-static laundry spray and waft it around liberally over cables and around components. Not directly on the turntable or record but around it. Longer term you may need to search Amazon for liquid pump sprays that are more longer lasting. You will probably be spraying Static Guard every night. That's what I do. 

There’s also carbon fiber brush gizmo’s that contact the record and provide a path to ground during play. Get one.

Then as far as overall noise, it can be narrowed down to two main sources: anywhere, and everywhere. That’s not a joke. It can be one thing, anywhere, or it can be everything, everywhere.

Carefully take everything apart, down to the cartridge clips. Carefully clean and examine. Look for the tiniest detail. Especially where things connect. One miniscule weak solder or clip can do it. If the cartridge clips aren’t tight, crimp them. To do this safely, insert a round toothpick first and then crimp. The toothpick will prevent you from squishing it flat in case you’re a spaz. Check RCA connections the same. Use your contact cleaner/enhancer of choice, or plain alcohol and clean 100% cotton cloth.

Analog is not digital. Gain or amplification when playing a record is orders of magnitude greater than anything else. Some amount of noise is inherent, or more accurately can be insanely expensive to eliminate. Even then it will always be more silent with digital than analog. The noise with digital is the signal itself. The noise with analog is extraneous and this makes it easier to hear. If guys can learn to love the noise that is digital then certainly we can learn to embrace the suck.

So, is the noise you have left normal and live with it or too much and do something about it? My simple test: turn the volume up to as loud as you normally like to listen. Sit in your chair. If you can make out the noise, its not bad but you can hear it, that’s normal. Or maybe I should say acceptable. Live with it. Because when you drop the needle, almost always even a really quiet record will have groove noise at least that loud.

If you do all the above and the noise is a lot worse than this, well let’s cross that bridge when we come to it.
