Oooooooooops.  Well, chalk that one up as a learning experience.  And
thanks to all who corrected my inaccurate description of transformer

When I designed my DIY heating cables, I sought out a transformer that
included a rectifying diode to convert the output to DC.  I was under the
impression that this was standard practice (for the reasons mentioned in my
earlier post).

I would highly recommend that anyone doing DIY heating cables use a DC
supply voltage.  And I'll reiterate Steve Pushak's message:  Safety First.
