MULLARD, GZ32, NEW BOXED, JUNE 1966 BLACKBURN PRODUCTION, CV593

This Mullard produced GZ32 valve shows excellent bright getter and tests as GOOD using my AVO VCM163 valve tester. The black base is tight to the envelope and carries a  white ink cartouche on the envelope.  The etched factory code  denotes a JUNE 1966 BLACKBURN production date

Device test data: Ia = 60.0mA range, GOOD  A1 91/ A2 90.

We test our rectifiers using a calibrated and standardised AVO VCM163 on the specified range.  This VCM gives a qualitative estimation of emission as you can see from the photo, the GOOD range bar runs below the numerical uA/Ig scale with the GOOD range between 51 - 100.  The above device test data, shows the max current range specified and a record of the numerical reading within the GOOD range obtained.
