Radio Valve Testing Service

Avo VCM163

Please note that effective 2.6.19, we are not offering a valve testing service until further notice. It is unlikely this will be sooner than October 2019.

We can test almost any kind of radio valve using our AVO VCM163 tester, whether the valve is a low-power device from a radio receiver or a high-power valve from a large audio amplifier or industrial equipment. We have gone to great efforts to ensure our 163 makes reliable measurements; calibrating valve test meters requires some effort.

We have test data for all makes of valve including Brimar, Marconi, Mazda, Mullard and Phillips as well as several makes from the USA (e.g. RCA) and other countries.

Occasionally, we are asked if there is any way of rejuvenating old valves, but valves which have already been in service for long periods of time have usually undergone changes which cannot be undone.

We are frequently approached by people who have acquired a ‘box of old valves’, and want to know how much we would charge to test them. We generally don’t quote for testing individual valves and request that you send us a list of the valves you have, preferably showing how many of each type and whether or not these are believed to be used or new. There are thousands of old valves around; some are worth pennies and some are worth many pounds. Valve-testing is quite time consuming and testing valves with little or no value is unlikely to make sense.
