5U4GB GE OWENSBOROUGH SHORT FORM 5U4
This GE short form 5U4G valve shows excellent bright getter and tests as EXCELLENT using my Avo VCM163 valve tester. 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.
