This one is super rare and the sound is deadly quiet. It’s worth every penny. The tube was carefully tested on my TV-7/U and my hifi system with NOS values at 98-102/56 min. What you see is what you get.

The tubes are super rare, hard to find and in mint condition. All the tubes are carefully tested on my tube tester TV-7 at NOS range. I'll give you testing photos before sending them out.
