As I promised, the circuit is reposted and your other JT circuit is included.

Looking the way the flash circuit has a seven winds coil over the other two. I compared it with @mk1's idea and a light turned on inside my head.
I did this version of a transformer. I took the toroid and added the seven turns of wire over the other winding and connected as the audio transformer is connected. I will let you know what hapened.

I tried all the transistors I have on this transformer and does not work configured as the audio transformer that suppose to go in that place.
By the way, the pot that is supposed to be used, was too big for the space and too difficult to connect, so I used the transistor formula posted before instead.

Edit:
Connected as it is, the LED should light and it is not.

hey Jesus which Schematic are you using ? Mine ? EDIT **** never mind i look back a few and i see you are trying Mk1 mod

Theres no reason My circuit couldn't work powering your motor and feeding back . If you wind a regular 40 turn Jt  then wind two more secondaries one with 12volts and the other 12volts ,replace the dc converter  and test run the Newman on the Jt output . you will need variable resistor in any circuit you put a load on to tune it for an output .. Have you tried that ? solder some wires on your pot so they can stick in the holes
