Product Description

The Heritage Avo, named because it's made from an original Avo Meter manufactured anywhere from the late 1930’s to the early 1960s. These were the definitive piece of electrical testing equipment and used by engineers, lecturers, electricians, and the military worldwide. An iconic piece of testing equipment known to millions of engineers of the era.

Each Meter has its own story to tell and can range from an early MK 7 up to an Avo 8 MK III. They are all original, and may show signs of wear. Some have handles, some are missing – it just depends on the life each particular meter has had. It is a random selection which one you will receive.

Once received, each Meter is then carefully cleaned, and any broken glass is replaced. A Nixie Clock is then fitted into the dial, so the meter can be reused for years to come!

Nixie tubes were invented in 1955, and were a means for early electronic devices to display numbers. They consist of a clear glass tube, with the numbers from 0 – 9 are stacked behind each other. The tube is filled with neon gas and then sealed. Each digit has its own connection, and when a small electrical current is applied, the neon gas around the digit is ionized, which causes the distinctive orange glow. There is no heat produced, so the tubes can last up to 20 years.

Paul Parry

Bad Dog Designs founder and electronics engineer Paul Parry grew up dismantling and sometimes successfully reassembling all kinds of electronics and devices. His first Nixie tube clock was assembled on a whim—without even realizing the appeal of the steampunk aesthetic he was creating. The passion project has since evolved into a full-blown entrepreneurial endeavor, employing both Paul and his wife Karen full time. Bad Dog Designs earned a Merit award in the International Arts & Crafts Design Awards in 2016. Paul is also a recognized artist by the UK's Craft Council, and works as an artisan on the BBC's "Money for Nothing" TV series.
