Filament transformer question

[deicide67]

this means it operates at a mains frequency of 400hz, right?

What happens if you use it at 60hz?

Thanks!

For a filament transformer designed for 115V at 400 Hz but used at 60 Hz, the input voltage must not exceed 115×60/400 = 17.25 (VRMS), so obviously the secondary voltage will be practically useless.

Thank you!
