Philco 212
#9

It is typically the primary, for it is the one being the heat-dissipating load of a tube. The secondaries are rarely open, and if they do, it is likely corrosion and not burn-out.

There is also using the secondary as an auto-transformer kindof, which is what Ron has in his article.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
