Turntable Hum

@danmar123 I’ll check the headshell wire...thanks

@millercarbon Unfortunately everything is conected to the same outlet / 2 power strips 

@noromance I did ground lift the TT motor & pulled everything in strips out 1 by 1 , no success

@millercarbon I'll try your suggestions, the only time the hum goes away is when the phonostage is out of the loop 🤷‍♂️

@femoore12 I did add a Marantz 2270 receiver recently but nothing inputted , just plugged in and I think I removed it to see , no change . 

@ei001h I moved TT to the floor , no change , I'll try the cable jiggling. thanks 

@millercarbon 

when I disconnect the Phonostage all humming goes away . 

unplugging TT from phonostage completely the higher buzzing is gone , but a low end hum remains....the high buzzing comes from the right side of TT 

thoughts? 

@mr_m there is no power supply , just a cable into wall for motor 

@millercarbon tried different outlet on phonostage & preamp , no change ...

could the power cables for any of my units be malfunctioning causing this? I could swap...

@rauliruegas Turntable & phonostage are grounded 

@aberyclark tried different RCAs from TT to Phonostage , no change...

@millercarbon thanks..when I disconnected the RCAs from TT to Allnic & inputted 1 by 1 I noticed on the right input a slightly higher pitched buzzing , nothing major , just slight...electrical , emanating from speakers for sure..I'll try moveing the allnic to anotehr system & see if its noisy....Arent these Phonostages kinda inherently noisy because they are boosting the signal so much? 

@swanny76109 The Allnic 1202 Phonostage is almost brand new...I do notice when I tap on the cylindrcal tube cases I get a fair amount of feedback through the speakers ...noisy...thanks 

@millercarbon really appreciate your time on this matter , the hunt continues...I'll post soon...

@audio-union and of course I will go down the rabbit hole of what cart works best with my set up 😃  was investigating the AT ART-9 , have heard alot of positives . I'll try a different power cord on Phonostage...thanks 

@audio-union I will check the power with my multi meter ...thanks 

@cakyol no idea on tonearm grounding...it's a VPI Super Prime Scout w 10.5" tonearm....I know the headshell on Hana cart is grounded 🤷‍♂️

thanks 

@browndt thanks for the tip , I tried some high end Mogami's on the TT to Phono stage , didn't do anything ...🤷🏻‍♂️

@discnik the phono pre uses 3 prong power cord . Ive already tried plugging it separately in a completely different outlet & ground lifted it as well...no change .

I should say that the hum happens slightly at about 1/4th volume & it is really noticeable at 50% up....thanks
