Looking through my parts here I found a Jensen universal audio transformer, atttached is the directions looks like if I want to drive a 6 ohm pm voice coil I need to know the tube resistance. I have push pull 47's. Therefore if I look up the 47 tube in a tube manual am I looking for "load resistance"? if so it is 7000 ohms. So do I double that ( because i have 2 tubes) so that would put me at 14000 . if looking at this chart so on the secondary of the audio transformer would I use lugs 2 & 4 and go with what is close which would be 16000 under the 6 ohm column to connect my PM speaker to?
