Up for sale here is this beautiful used National Union 5U4G hanging filament coke-bottle rectifier vacuum tube. This has a 1944 date code.
I tested it on my B&K 747B tube tester, and it pegged the meter at 120/120, with no shorts or grid emission, on a scale of 0-120, where 65 is minimum good.
This is a gorgeous tube, with smooth black plates, hanging filaments, a huge round mica plate with two side mica "snubbers" at the top, and a bottom wide D getter. Th...is is quite a tube, that's for sure. This does have a slightly cracked base, but it won't affect operation. This is guaranteed to work well for you. Please see my pictures for details.
US shipping and handling is $4, and international is $14. I accept Paypal. If you have any questions, please ask.
I have a number of other tubes & sockets and other vintage electronics listed--feel free to take a look!
