I agree that older equipment was indeed designed to operate from a wide
range of line voltage. Most components in tube-type gear will withstand
quite a bit of overload before eventual failure, over time. The one
component that does deserve protection is the power transformer. As a
consequence of age. It's always a good idea to reduce heat generated in the
transformer due to higher than normally anticipated line voltage. I'm not
sure where the idea that line voltage is higher today than it was years ago
came from. As I remember it from my shop class in high school back in the
early 60's it was 117 volts. I would like to know where I can find the darn
specifications for my own curiosity. A quick look at the Allied catalog
shows line voltage between 110 and 120 volts as the line voltage
specification for transformers.

I seem to recall that the older gear was generally made to operate anywhere
between 95
and 125 volts, in order to compensate for the less stringent voltage
regulation on the
power lines of those days.  Whether this is true of Heathkit and similar
gear I am not
sure, but would be surprised if it were otherwise.
