Hum with new 6N1P-EV
09/27/22 at 16:32:30

Hi guys, I purchased a couple of Voskhod 6N1P-EV tubes to use as a backup in my new UFO2 and both make the amp hum a lot. The one that came with the amp works fine obviously. I’m surprised as both tubes come from a reputable online seller in Canada and were professionally tested prior to shipping. Any idea other than I was sold defective tubes? Thank you much.
