It seems that MM has changed to terminals for some of the wires on this PT.

Here are a pic and a diagram for the new version.

With regard to our JTM 45 kit:

Select the correct color primary wire for your operating voltage.



RED 230V


The terminal labeled "COM" will replace the orange wire indicated in the instructions.

Terminals 9,10 and 11 correlate to the green heater wires. With 10 being the center tap which gets grounded.

Terminals 12 and 13 correlate to the yellow rectifier heater wires.

Terminals 6,7 and 8 correlate to the red high voltage wires. With 7 being the CT which goes to the fuse holder and then to ground.
