Not sure why you would specifically want to use an isolating transformer with this set which has a double wound mains transformer and earthed chassis. An autotransformer or variac would serve equally well. As Kalee20 said, a few minutes plugged into a higher voltage won't hurt the set and will allow you to check the heater voltage.
