I have now been able to pull together the appropriate settings for my Precision Series 612 Tube Tester to enable me to test the ARP-3 Pentode valves for my 52-Set Project, using the British Valve Adapter I was able to build.
A long overdue Calibration Test of the tube tester revealed no serious problems, and i was able to do three consecutive tests of the same ARP-3 valve and get readings within two points for the three readings. Quite pleased with that.
