Ya so the best I can figure is that it is an RCA 2A3-D type, which has separate plates compared to the more common RCA 2A3-B type which has dual filaments and grids but sharing one plate. (Commonly called bi-plates)I can't comment on the flashing, but I suppose if it is unique to that "D type" tube then it may be OK>

Either the amp you're running it in is unstable, or might possibly use a higher B+ than this particular Bi-Plate 2A3 can stand.
Biplates aren't the Cat's Meow. The JJ 2A3-40 is rugged!

Just to clarify, the tube appears to be a "D" type dual-plate, not a "B" type Bi-plate, if that makes a difference.
Thanks for the help. The flash startled me at first because I wasn't expecting it, then it played wonderfully. So it seems to be good to go. Thanks again!
