OK...
 this is a bit weird. This tube has ALWAYS been brighter in this TV, the 1st video amp, 6AU6, it flashes MUCH brighter when first turned on, then dims down a bit, but is always brighter than all the other tubes, but always seemed to work, an RCA branded tube. may be one of the original tubes. http://suzaku.live-evil.org/0209241844b.jpg Just to see what would happen, stuck in a NOS sylvania, and it warms up slow like the others, and is not as bright as the RCA that was removed, not seen a tube act like this before, almost as if they mis branded a 4AU6 as a 6AU6 :O weird.

Most likely, just know that it IS an RCA, could be an original from when the set was made.
Hard to see any kinds of date codes on it, not sure how to decode them anyway,  Looks like under the “Made in USA” 8 (or B)-71. No idea if that's what it says or what it means.

Thankfully the planet is still littered with NOS 6AU6's

Cause the video out was acting a little weird, I have some NOS tubes on the way to replace what's most likely 50+ year old ones. Thomson France 6AU6WB Military Grade (1st video) I had other 6AU6s, but, you can't turn down mil spec! 6K6GT (2nd video-output) thank you audiophiles for making this tube cost more than it should. 6AL5 (video det/ dc restoration) the only tube not with an inflated price.

A weird thing about this set is, the schematic shows the HV to be at 9k, which is the nominal voltage for a 10BP4, standard CRT for the RCA 630TS of which this is a clone of.
HV tests puts output at 10k at mid brightness. However. FADA put in a 12LP4, and specs show that to have a nominal voltage of 11k. Did they flub things a but to put this tube in? It does work, but I can turn up the brightness to a point that it overloads the HV and blooms. W/O a load, the FBT is putting out about 10.2k, this seems OK for one made for 9k. :O
