Selenium Rectifiers
I have an old textbook on T.V. repairs, which says of Selenium Rectifiers-
"Failures in this type of rectifier are characterised by a remarkably unpleasant smell"
Boy!! did I find that out, AND what an understatement it was!!
It was many years back when I was still living 'at home' with my parents. I powered up a set, and there was a tiny puff of smoke from the rectifier... Minutes later, my parents were most unamused to have all the doors and windows open in the depths of Winter, trying to get rid of the Godawful Stench which had pervaded every room in the house.
It was a lesson well learned... From then on, anything with old 'metal rectifiers' in it got powered up outside first!!
Thanks for the memories...
