imhififan,

I received the following readings (all in ohms)

Black - Brown 1.3

Black - Red 1.6

Orange - Yellow 1.4

Orange - Blue 1.6

I hope that this information will help. 

Thanks

@pip555

Thanks for the measurements, the readings confirm that brown and yellow are 100V windings, red and blue are 120V windings.

You can go ahead to move the jumper wire J1 to J4, J3 to J5. That will change the voltage setting from 100V to 120V.

imhififan,

Thank you very much for your assistance.  I will try to make the changes in the next day or two.  I will give you an update then. 

Cheers

imhififan,

The changes were made, and everything is working perfectly.  The drawing of the transformer taps was extremely helpful.  Thank you very much for your assistance.  

Cheers

🥂

I'm glad to be of help🙂
