Last night i rolled a bunch of tubes on DV
Concluded that any noise/hum i heard is due to driver tube on the front.
Stock chinese - hum in left channel
GE 6sn7gtb - both my tubes were decent sounding but still put out mild audible hum in both left&right channels
Sylvania 6sn7gtb - crunch/arcing noise in one channel at times, But no hum
TungSol russian 6sb7gtb reissue - both of them sounded like car enginee was turned on. Loud audible noise into left&right channels
TungSol USA 6sn7gtb - almost silent. Very mild hum and these sound great. Best of the bunch
