5V4G, MULLARD, CV729, BROWN BASE

On offer we have a Mullard  5V4G rectifier valve.  The classic ST envelope is tight to the brown micanol base.  The envelope has the standard Mullard branding on one side with the obverse showing the military code CV729 along with a pheon arrow - a military supplied valve  The device tests as GOOD for each diode section using our AVO VCM 163.  

Device test data: Ia = 6.0mA range, GOOD  A1 81/ A2 84.

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.
