RE: What Tube is this???







It is a Chinese 12AX7.

I have a box full of them (Mesa and Ruby branded) with 2 posts to the getter. Hard to see in the photos, but there are two there.

I believe they are older production (1990s).

The Sovteks have a characteristic saucer getter, while the Chinese tubes have this single dimple rectangular getter.

I also have some Chinese 12AT7s from the same time period, and they have two posts to the same type getter as well.

By the way, I find these older Chinese tubes to be decent - very accurate in my opinion. I have, however, not used them extensively. I understand one main issue with them is longevity - they drop off quickly.
