[QUOTE="charles, post: 1019589, member: 2759"] Before certain valves listed in the AVO data manual is a square symbol. When testing the inter-electrode resistance of these valves (hot or cold) these valves may be damaged when using the earlier generation of AVO valve testers. Quote from the AVO data manual (1981): "The earlier generation of AVO valve testers should not be used for inter-electrode insulation testing on these few types, because the test voltage used is 150V (peak). The limitation does not apply to the tester VCM 163 where the test voltage used is 50V d.c." One of these valves listed is the E88CC [/QUOTE]
