HELP with an intermittent static fuzz noise in right channel! Is this bad tube?
I am looking for help. Recently had a fuzzy sounding static noise of varying intensity starting in right channel of my 2 channel system. REALLY Notice it when volume at ZERO.
I have tried all the traditional remedies for ground loop, RF noise,loose plugs, ect...
My system is a Vincent 237 integrated with streaming from an Allo Usbridge dual powered with the Ciunas Supercapicitor battery psu. Streaming Tidal via its Volumio app. I have either the MDHT Orchid DAC or CARY DMS-500 as DAC/Streamer on 2 different inputs of Vincent. I utilize Fuhrman PS-8 Digital power strip on every power cord/charger but the amp. I have changed around the cord mix f La Esplada power cords and stock PCs, different RCA and interconnects,coax,ethernet,USB: which is mix of Morrow, Audioquest, Blue jean, Wireworld,and Supra.
The entire time I assumed it was electrical noise , RF interference, WIFI reception from my WYZE security cameras, or cords that touched interconnects......, well so far WRONG. Its now here coming and going everyday reducing my noise floor.
Does this sound like tube issue in the Vincent 237? I purchased used from Music Room September 2018. Worked fine up until the past month.
thanks for the ideas!
