AVO Mk 3 tube tester for sale. Used to belong to Bill Beard.
The tester worked fine for me but then developed unstable readings on the Meter Tester switch just under and right of the meter. The other functions appear to be OK and the meter looks to be OK. I can't actually diagnose the problem because I don't know enough about the internals of AVO testers. Maybe the switch needs a clean, maybe something else. I started getting intermittently good readings and then the needle went unstable and I couldn't get a stable response. The meter works fine on other functions. I haven't used the tester for a few years now, and it has always been kept in a warm dry apartment.
So - looking for a good home. I'm thinking £750 and will be advertising elsewhere as well. Needs to be collected from Kensington W14.
