EXPIRED For Sale AVO MK 4 Tube/Valve Tester

Further Information

Hi everyone, 

This AVO MK 4 Valve Tester was my dad's gear before he passed and we are looking to clear some space. We have used it to test some valves before selling recently, so we can assure that it is in perfect working condition. However I am not knowledgeable in the specific technical aspects of its working condition (recalibrated? internal workings etc), but the price should reflect this fact.

Per the photos, the physical condition of the valve tester is not mint. The left and right readers are perfectly legible in person, although it is oxidised and no longer black. It also doesn't have the top lid, but it never did in all the years in my dad's possession anyway. It also comes with the 14th edition of the manual. From what I gather, there should be another 'working instructions manual', unfortunately we do not have this in our possession, so please keep this in mind if considering to purchase. 

The price is to reflect the condition of the valve tester with full transparency to its working condition, as we are selling it as it is. I am happy to answer any questions, please feel free to reach out.
