Field coil quandry
#18

Like you said, I can measure the current needs using a 6100Ω resistor, providing everything else works ( I just recapped and rewired it), but how am I to determine "any speaker that uses a field coil that takes the same current (or close) as the original speaker" on a speaker that I find on ebay?
