5U4G, MARCONI BADGED CANADIAN WESTINGHOUSE, SMOOTH CHARCOAL ANODE, VT-244, 5U4
This marconi badged Canadian Westinghouse tall from ST envelope 5U4G valve shows excellent bright getter and tests as EXCELLENT using my AVO VCM163 valve tester. The black base is tight to the envelope.
Device test data: Ia = 120.0mA range, GOOD A1 66/ A2 68.
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.
