Nope, they had the PDM MW-50 modified to an SW-50. There is apparently a problem with the fiberglass chimneys for the tubes. As they age, they become more prone to carbon tracking and breakdown, which is what happened.
Funny, Allan says he wants to go back to a conventional push-pull high level modulated transmitter....I would advise against this, as his power bill might double.
Also He did mention there was no insurance. Most of the radio stations I've worked for had some form of business insurance. I can't imagine running one without. In this business, you have a lot of exposure, towers that fall, buildings that burn, stuff that is pretty expensive to replace.
Just a thought,
