Got my hands on a fixer upper. In the 115 position, the primaries are open, in the 230 position, I get 67 ohms which should mean (2) 33.5 ohm primaries. I removed the 115/230 switch and wired the primaries in parallel, I get around 17 ohms. Before I fire off fuses, I thought I would query the troops. I did contact the MFG...waiting to see if I get a response...

Thanks

Stuben
