This NEC-TOSHIBA SHORT FORM envelope 5U4GB valve shows excellent bright getter and tests as EXCELLENT using my Avo VCM163 valve tester. The black micanol base is tight to the envelope and the electrode cage features a 5 ribbed charcoal anode electrode cage - all the sonic character of it's ST enveloped brothers but in the short form 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.
