AVO Mk3 Valve Tester. V Good Condition & Working Order.

AVO Mk 3 Valve Tester

As you can see from the photos it is in very good cosmetic condition

Everything is clean & tidy internally - I have tested the two GEC D77 valves (with another valve tester I own) and they are strong, well balanced, and show no faults.

It will test just about any valve from the 1920s onwards

It is in full working order

I'm not sure when it was last calibrated, but test results are very similar to my other valve tester (which was calibrated recently)

The instruction manual has lost it's front cover, but all pages are present and settings for testing each valve type are listed

I will pack double boxed with plenty of protection

Postage cost is an estimate; if it turns out to be less I will refund the difference and if it is more I will pay the extra myself

Thanks for looking
