6X5G, TUNGSRAM, NO ENVELOPE MARKINGS

Device test data: Ia = 30.0mA range, GOOD  A1 73 / A2 77.

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 maximal value of which varies due to valve type and intrinsic rA.  The above device test data, shows the max current range specified and a record of the numerical reading within the GOOD range obtained.
