[QUOTE="charles, post: 735532, member: 2759"] Ia and Gm readings for six CV 1947 valves: AVO 163 settings: Vg1: 18 Va: 350 Vg2:250 Ia: 54mA Gm: 5.2 mA/V Actual measured readings V1: 54mA 5.2mA/V V2: 51mA 5.2mA/V V3: 55mA 5.4mA/V V4: 55mA 5.2mA/V V5: 55mA 5.5mA/V V6: 52mA 5.1mA/V As can be seen these readings are very near each other. If have more time available I may measure another 20 or so of the CV 1947 valves Ampdog: I will measure the two valves in order to proof to you that the CV 1947'diameter is actually smaller than the KT66. If am correct your information is the same as that in the RCA valve tube manual (1942): 2 1/16 inch It may even be that different makes of 6L6G valves have different diameters. [/QUOTE]
