Resistance is meaningless in this situation. What you need to know this the impedance of the pri and secondary. What you are looking for is one that has a 7000 ohm to 2 ohm (impedance not dc resistance). In reality a transformer that will match a 2A5, 6AQ5, 6BQ5,6K6, 6F6, 6L6, 6V6, 41, 42, 47, 6005 ect.. to a 4 ohm spkr is fine. Most of the aa5 transformer are kinda low in impedance (abt 1.5K)

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
