I remember this type was popular in the 80's, and I'm interested in knowing who made it.

It has a metal tab attached to the getter support. The tab has an imprint, but I can't read it.

It's excellent as the first stage in a guitar amp, with very low microphonics.

It looks like a Tungsram vacuum tube. The tag is a give away for Tungsram tubes.
