“It is seemingly an improvement over the stock jj 12au7 installed in my preamp. Of course it could just be me wanting to hear a difference. Its difficult to do an A/B comparison. However, the ge Is quiet and it has lessened the hum I was hearing prior to using it, it is virtually absent now.”

“I've rolled several valves through my AN 4,1 and finally found the one I will stick with. Beautiful tone. Very clear and musical. Very high quality valve.”
