Allnic H-3000 hum when mute button engaged.

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.

Late to this thread. Glad you figured it out. For future reference, Roger Modjeski of Music Reference is authorized to work on Allnic gear. He’s up here in the SF Bay Area. Terrific guy, and one of the most knowledgeable techs you’ll find.

Thanks wrm57,

Hello dangcaonguyen,

Excellent news on solving your hum issue, thank you for doing this research for us.. :)

Regarding the rectifier, I have tested many, and have a few favourites that to me and friends are stand out options: KR Audio 5u4g being the first, a wonderful match and so full and open sounding. Second is not generally available off the shelf so to speak, and it is the Ayon 5u4g. It is a large tube which requires a simple mod to fit into the psu case, but it is all that the KR is with tremendous bottom end drive, and is probably my favorite. Next I will test a KR Zirconium 5u4g, if this can improve on either the 'standard' KR or the Ayon, I have my phono stage to grow old with.. Have fun.. btw, none of these are cheap!

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