50B2 (50B2) 

Hoping someone can change some of the descriptions. I have posted a pic of the 50B2 tube. This type of tube is an iron in hydrogen type power supply. The base is a medium 4 prong ST bulb type (not octal).

Regards.

D Leishman.

50B2 or 150B2 

The new picture of this tube seems to be a 150B2 with first "1" missing.

150B2 

The 50B2 is Octal Ballast Tube, and  drops 50 volts at 300 ma, used before 1939

The 150B2 is voltage regulator and runs at 8.2mA and is B7G. B7G only since 1939.

 

So I agree, it looks like a 150B2 with 1 rubbed off.
