Name that EL34!
 
The 2 tubes linked below came from a Dynaco ST-70 that I bought. There are 2 pairs of them. To thisgreenhorn, they look like Mullards. They are stamped "Made in Great Britain." One has a single halo getter and the other has a double halo getter. There are really no other distinguishing markings on them (other than the pin numbers, which I doubt are neccessarily distinguishing).

Tubes in general are pretty new to me, so please try not to laugh too hard at my inability to accurately identify these tubes.

I also received 2 RCA black-plate 7199s with the amp that look mint!

Tube 1 with single halo getter:

Tube 2 with double halo getter (the second image makes the halos look stacked atop of one another - this is due to the angle of the snapshot):

Look like Mullards to me.

Have a look for a brown two line code near the bottom of the glass it should read Xf2 , 3 or Xf4 or similar... That would tell you for sure.

Also be careful of the printing- if you clean these tubes, don't wipe off the print!

Thanks, Shifty.

Tube #2 with double halo getter is certainly a Mullard:

Tube #1 - with single halo getter is marked "GT BRITAIN," has stapled plates, and a crosshatch on the top of the glass:

In my haste, I neglected to closely inspect tube#1's partner. It appears to be GE branded with a marketing name that I don't recognize, but is otherwise the same:
