It might drop out, I didn't try that. It seemed in there pretty tight though, I did try bumping it on the edges before trying to pull it out - it's not moving or loose, but I'll try turning it over and induce looseness...
That is what I thought would work too, a thin nose pliers... unfortunately my tool kit with various needle nose pliers is elsewhere, and the spare kits I have here - don't come with a pliers kit - only those 3 tweezers, and pry tools. I may be able to use some straight rod / bit's to leverage it out from the inside of the post. Even sticking in only one tine of a pliers with it's serrations on one side should have enough grip to pull it loose.
The tube only cost me $30, so I'm not out that much, but it might be worth the practice for when I have a more valuable tube to fix. If the tube had worked ok - without the presistent buzzing - I might be more inclined to save it - but who knows - perhaps a better bottom fitted on will fix that buzzing problem too.
It looks easy enough
Here is a view of the TA-26 PCB outside of the case, the raised socket on the front edge of the board is the 6SN7 socket, and the socket in the "middle" of the board is the 6AS7G socket, the one with the stuck center post:

It might be the 2D perspective, but that socket doesn't look very deep and it doesn't look like the motherboard has a matching Hole in it to accomodate a long center post. I wonder if that might be the source of the problems I've had with the first two FAA-6080WB tubes not seating well? I wonder if a tall socket saver might be helpful in fitting 6080's properly before inserting in the TA-26 socket?
