[Boatanchors] 6146 A or B ?

[Glen Zook]

GE specially "culled" a number of their 6146B/8298A tubes for Heath (primarily to use in the HW-101) that were not so "touchy" in terms of neutralization and so forth.  Those tubes were "cross branded" with the 6146A/6146B nomenclature.  They may have done a similar thing for other radio manufacturers.

Now if you want to see some 6146 tubes with a real identity crisis you need to obtain some FADF marked tubes.  I have a couple in my "collection" of 6146 family tubes that are marked only FADF/USA (nothing else anywhere on the tubes).  The letters correspond to the number of the letter in the alphabet.  That is

F is the sixth letter so F = 6

A is the first letter so A =1

D is the fourth letter so D = 4

Therefore, FADF = 6146.

I picked up a pair of 6146's over at the evil empire and thought they looked strange when I got them.
 
They are both GE's, same date code but they are marked 6146A on one side and 6146B on the other ??
 
I have heard of people with an identity crisis, but tubes??
 
Maybe they are 6146A.5's or maybe 6146 wanna B's ??  
 
The markings are real, not fake. Just never saw anything like this before on a 6146.
