Allnic H-3000 hum when mute button engaged.

Also the hum went away when the switch is on the operating mode.

Thanks Lewm.
I am finding the way to get access to the inside. Do you know it from the front or from the bottom of the unit?

@yogiboy The unit operates perfectly, and the music sounds awesome. I really don’t want to return it. And I think the mute button is sn easy fix. I am contacting the seller to see what he will say.
@lewm I know how to soldier, it just I am afraid I will damage the unit by opening it up the wrong way. I have made my own intetconnects, so I think this job is not hard for me if I could open it up. 

Hi Lewm,
Here are the list of my components:
 Garrard 301 with 2 tonearms:
Moerch  DP-6 with ZYX Aries 3 Moerch  Phono Cable
Polstar PS-UNV2 with ZYX Omega Gold, Polstar phono cable
Allnic H-3000
Homemade Silver IC
Shindo Aurieges
Shindo Interconnect
Shindo Montille EL84
Belden Speaker Cables
Devore Fidelity The Nines

I dont have any balance IC to try for now.
I will switch my homemade IC to the MIT avt1 IC to check.
 Thanks for the suggestion.

Also the hum in both channels and only at the Mute Position. 

@whart and @lak 
Thanks for your suggestions. I will contact Albert, but for now i am still waiting for the answer from the seller before moving forward on what to do with the unit. It is strange, I have emailed him for 2 days without answer. He might not checking emails over weekend.

I am on the west coast, Southern California. 

@lewm I switched the interconects to MIT, the problem is still there. 
You are right, when I stand with bare foot and touch the transformer’s gain knobs, the hum is gone. The problem is the ground disconnect while on the mute mode.
@whart Thank you, I will wait for a day or two to contact Albert. But as of right now, I trust the seller with his excellent reputation. I think he will contact me tomorrow when he is back to work.

Thanks everybody,
I got the message from the seller. There is the toggled switches on the back of the unit fir changing between Balance and Rca outputs selection. He suggested I check it on first (which i forgot to do). I will do it this evening and report back.

Hi everyone,
I am happy to report back that the problem is fixed. Its just the switch on the back of the unit. I firgot to switch it back to RCA. (What a stupid I am). Please apologize for my ignorance.
Now I am very happy that the H-3000 is as quiet as a tombstone.
About tube rolling, what are you reccomend? The seller already installed the RCA nos rectifer tube on the power supply. But if you know pf the better tube please tell.
 Thanks 
Calvin

Thanks Theothergreg

Thanks everybody. I am glad as nothing serious happened.
I am sure that I will do tubes rolling in the next few months. I am very satisfy with the sound i get with the RCA now. But who knows...
Thanks again.
Calvin

@ps68 is the KR ampizator the one? I see it on ebay for $600.
Thanks

Thanks ps68 and pops,
I will try it when my budget allows. 
As of right now, compare to my Zyx Artisan 2 and H-1201, I am enjoying my new h-3000 a lot more. 
Thanks to all.
Calvin

Just ordered the CBS/Hytron 5U4G ST to try. Will report back in a week or two.
 Thanks gents.
