I have located a speaker that will fit. But, the field coil is 2600 ohms, which puts it 800 ohms higher than the original. I know that one can roughly go 300 ohms higher than the original value, without affecting the B+ voltage too much. But those calculations are also based on a +- 110 volt power source. Out here in rural Alberta, where I live, the line voltage is running 128 volts. Does anyone have experience using a speaker with a higher field coil value? Maybe the B+ will still be ok? Any issues in doing that, which might affect the power transformer?
