I'm not sure where this NOS tube was made, China, Russia. But it solved the problem for me. Maybe it was just happenstance, but I had a lot of trouble getting rid of hum from the preamp and power amp sections of a home brew tube guitar amp. I read in a forum online that often hum comes in the phase inverter stage, which is a 6SL7GT in my amp. I originally got that tube from Antique Electronic Supply, a new JJ tube. JJ tubes generally seem to be of good quality. But since sometimes there is the odd tube that has problems, I tried getting another JJ 6SL&GT, but there was no difference. I knew that the hum was coming mostly from that PI stage, but I just could not find any problems there. Then I read that the problem at the PI stage can be from the tube not being balanced. Another person in that forum pointed out that some imbalance in that circuit might cause some distortion, but not necessarily hum. He suggested that using a balanced tube may solve the problem because it is of better quality overall. Whatever the reason, I actually tried a third 6SL7 tube, this one being the Tube Amp Doctor, Premium Selected NOS tube. As best I could tell from the description, this tube was selected for balance between the two triodes among other things. In any case, to my shock it actually significantly lowered the hum from the power amp section. Thank god, or at the very least, thank the internet and products like this old, carefully selected tube.
