Hello, I thought I would show how I rewire a power transformer.

Here I create some coils that I will use to splice the new wire on to the old transformer wires. I figure twisting the splice together creates too much movement of the existing wire. The less the better. Note two of the coils are a little bigger. The bigger ones will be used for the 6 volt winding. I use 20 gauge for all wires except the 6 volt winding which I use 18 gauge. To create the coils I wrap 7 turns of 22 gauge wire around a #14 gauge solid copper wire. I use #12 copper wire for the 18 gauge wire.  
   

Here I have attached the new 6 volt wire to the old by placing the coil over the old stripped back wire and then sliding the new into the coil. No twisting.
   

Here the 6 volt wire is soldered and ready for shrink tubing.
   

Here the 6 volt wire is completed as well as the 6 volt center tap. 
   

Here is my 6 volt center tap wire. I used a green marker as the tracer on the yellow wire since I don't have the proper wire. Should be green with yellow tracer. For the high voltage center tap it is yellow wire with red marker for the tracer.
   

Here is the finished transformer ready to go back in the radio. I have done several of these with no problems.
   

Hope this helps someone out.
