the noise is not come this amp, switch sound source and rca cable.So the I got the DV up and running. I redid all the wiring and soldering and the Alps 50 works perfectly. The only issue I have right now is that I get a high pitched background noise. Did I not ground it good enough ? The RCA, pot & headphone jack are all grounded. I did not ground the wires coming from the 6sn7 socket. Would that cause my issue ? It's not audible when playing music so there's that. It could also be the tube I'm using humming like crazy and will go away in a few days but the noise completely goes away if I unplug the RCA's in the back. Any suggestions ?

Edit 2 : Do I need to connect these together (yellow drawing) so the loop is complete ? Sorry for the noob questions

I've tried Zen DAC, RME DAC, ifi RCA cables, QED performance graphite series cables, preamping it with the Elise... It still buzzes like crazy. I'm willing to give it for free just to get it out of my house lol

Does the buzzing increase or not change with the volume increase via volpot?

Are you sure it's not the tubes themselves causing the buzzing? Sometimes I've had power tubes crapping out on me when they start buzzing.
Also crazy (non-sensical) voo-doo coincidence reasoning - have you tried running the DV away from all the other gears around you? Not that it should be affected with all the super engineering and super shielded cables and such. Still I've for damned reasons found other things that just inexplicably interfere when its in the vicinity. This is probably a dumb idea but just one more thing to rule out before you send it to @JKDJedi the dying gears and tubes whisperer. LOL

OK What the actual... I unplugged my keyboard and it went away. Some noise hum after 12 1 o clock but that's just the DV... What is this voodoo ? It works. It actually works lmao and sounds better than ever
