BRIMAR 5Z3 BROWN BASE MANUFACTURED BY OSRAM JAN 1956

Well, what a special device, essentially a U52 mounted on a UX4 base, this is a superb valve indeed. Badged in black base print as a Brimar but from construction and faint cartouche is an Osram manufactured device this is scarce and desirable too. Showing perfect emission on test, will you give it a home?
