Re: Avo valve characteristic meter
Definitely a VCM Mk II
They're quite good mutual conductance testers, though the meter is not as sensitive as the Mk III onwards models, so their leakage tests are not as sensitive.
Two warnings:
1) it can be easily damaged by inappropriate settings of controls, so there is risk of damage from a previous user, also you need to read-up on correct operation before trying to use it.
2) Some people try to use valve testers to 'burn-in' valves. Don't! they are designed and rated for just quick tests.
I speak as someone who bought one as a teenager, and ruined the meter. I've regretted it ever since.
