Isolation Transformer Output
#1

I've got an old Triad N-67A transformer and the output is 128V. That seems a tad high and out of range of the 115 +/-5% spec. This seems too high to use for radio work and I'm wondering if it would work better through a variac that shouldn't be sensitive to 128V input. Anyone have experience with isolation transformer and their output?
