Philco 91 Speaker Replacement
#38

I see where the 10k ohms comes from in the tube data sheet. Where does the 95 turns ratio come from?

If I use 5.3 times 9000 I get 47, 700. There is nothing anywhere near that. Can you give me some examples if my voice coil measures 5.3 ohms?

What happens when the mismatch is not close?
