I think you already know the "brand". There are several names on them and they all come from Russia, or Russian former countries. In the photo its a Sovtek.

I have a Peavey amp on the bench now that runs 6BQ5's so only about 350 volts available.
The IC branded 22uF @ 500 volts have also popped their corks. Exactly the same failure,
dried up electrolyte oozing out of the end seal. I have been using F&T 22 uF @ 500 volts as I mentioned, and also havent had failures. I am sorely tempted to open up some of the stuff that I did fit IC caps to and check their worthiness.
