A call out to all the tube guys out there
I've just scored myself a AVO mkIII tube tester and i've got the operation manual. However i'm suspect about the calibration of the machine as i get consistantly low mA/V readings on most tubes i test. I'm after the checking and alignment info for the tester so i can verify if the unit itself is operating ok
