Rauland 12KP4 Aluminized CRT

[ohohyodafarted]

If you are puting it in a zenith porthole circa 1950, you will have to modify the chassis. There are some components toward the front of the chassis that need to be moved because the glass crt is wider than the 12UP4, and some of the components on the chassis will not allow enough room for the glass crt to fit. But it can be done, if you are willing to hack up your chassis. Otherwise you can wait around and pay the going price for a good 12UP4. They come up on ebay once in a while.

I paid over $200 for a good, EXTREMELY RARE 16EP4 several months back, and I would have paid even much more. As the saying goes, "if you wanna play you gotta pay".
