I'm guessing bias has nothing to do with it. It looks like contaminated vacuum. I'd shut it off before a transformer gets damaged.

So what do you think of those TechTubes? Seems to be very little interest over here about them.

A bit off-topic, but where you got sockets and top connectors for these tubes?

Good tube and low cost (one russian GU29 5 euros). I also have the QQE030/20 NOS from Germany ITT to test (7,5 euro). 30 watt for very good sound.

I've seen that enought times to know it's an extremely gassy tube that is way beyond redemption. I would try for a replacement from the seller. Send them that picture.
