I have a Farnsworth AC-70 and the output transformer has an open primary.
The output tube on the radio is a 6V6 (single). I have located an output transfomer from my junk bin. It is from a chassis with a push-pull 6V6 output. The two transformers are physically the same size. The one from the junker reads around 130 ohms on each side of the centertap with my multimeter, while the Riders 11-8 (Farnsworth) shows the original to have 550 ohms DC reisitance.
Can I use this output transformer to replace the original? Will I use it full winding or centertap to one side?
Thanks for your help,
