Questions about tubes and gear that glows. FAQ

RE: Tube ID

I am sure you are aware what a sylvania glass marking looks like. And as all the "recent" Sylvania tubes had a glass etched marking. I have a couple of different Sylvania 5v4g , ga, and none look like that. So not Sylvania would make it much more strange. The side rods are not familiar for the 5v4 maybe a 5v3?
