After many years of sitting in a rack gathering dust, one of the volunteers at Cambridge museum of technology has resurrected their mercury rectifier.
It used to run a large DC Motor from the new-fangled AC mains. But this was soon superseded by a replacement.
The Rectifier has lain dormant since at least the 70’s. The Museum has managed to get a supply to the anodes and enough current via it’s ignitor circuit to get the tube lit up and working (although at much lower power).
A fantastic achievement that shows the engineering (and beauty?) of these rare devices. Much better than an odd shaped dust covered glass thingy in a rack.
With thanks to all of the Coilers (and wives) who brought stuff and supported us, Staff and volunteers at Cambridge Museum of Technology who let us abuse their electricity supply for the day and the visitors who asked some great questions this year.
Watch this space for details of next years Teslathon at the end of October 2016.
