5U4G, SYLVANIA ,5 RIB ,CHARCOAL ANODE, JAN, VT-244

This Sylvania tall form ST envelope 5U4G valve shows excellent bright getter and tests as EXCELLENT using my AVO VCM163 valve tester. The black base is tight to the envelope and carries a slightly faded white ink Sylvania VT-244 legend in addition to the etched octagonal cartouche on the envelope. Device test data: Ia = 120.0mA for both diode sections

Device specification 120mA delivery for both diode sections. So you can see we have 100% emission from this venerable beauty.
