Don't know back in the day, but any decent transformer has "HiPot" ratings, namely the ability to insulate 1KVAC or 1.4KVDC. Vintage transformers may have been built for 600VAC isolation. The reason is to avoid breakdowns caused by transient spikes riding on the powerline. Same thing for X and Y death caps.
