HP 9810 A transformer

That is what some engineers at HP used to do. The low voltage source was an HP oscillator, don't ask me the model, with appropriate short-circuit protection, of course.

Knowing that something, most probably, on the primary side makes 6 A fuses blow means don't connect that to mains till problem fixed.

A function generator could be used for that purpose.
