300B Orientation so logo faces forward
 
So - I've searched high and low on the interwebs, and only come up with one link that describes this, but with no solid information.

If I want the logo on the 300B tube to face towards me - how do I want to orient the socket in the amplifier?

Pics would be great if someone has them.

That would depend entirely upon the specific tube and the tube brand you use. There is no standard for where to print the logo or the tube number on the envelope. It may vary for a given manufacturer, and almost certainly will vary between manufacturers. Afaik.

That's the best information I have on this subject.

Thanks - I thought as much.

Are you an expert in tautology, because you are an expert in tautology? ;)

I have 4 older Sovtek 300B's that vary greatly in height. There is 3/4 inch difference between the shortest to the tallest. The red logo is crooked, and randomly placed, and no longer red.

The early Shuguangs......they couldn't even SPELL the word China correctly. The tubes were "made in Chian." I have a Shuguang 211 that is an "Election Tube, made in Chian." The lablels are wherever they are, no uniformity at all. The tubes all still work though. Maybe the newer stuff is better?????

It would seem so, so it would seem.
