CV1863, MIL SPEC 5Z4G, STC, OLDWAY, BROWN BASE  NOVEMBER 1961 MANUFACTURE

This valve shows excellent bright getter and has the inverted getter plate situated down by the pinch. It carries the  Brimar brand on the base in grey ink.

However, more importantly it tests as EXCELLENT using my Avo VCM163 valve tester. This exquisite device has a black low loss micanol base which is tight to the envelope and the pins are clean, straight and uncorroded. 

Device specification 60mA delivery for both diode sections. So you can see we have 100% emission from this venerable beauty.
