Audio Output transformer info needed
#1

I'm restoring a Philco Model 46-431. The primary of the output transformer is open.

The schematic lists the primary DC resistance as 500 ohm; no listing of impedence.
I have a spare transformer from an unknown radio whose primary measures 200 ohm.

What performance issues will I encounter if I substitute this lower DC resistance transformer.
The audio output tube is a 6K6.

Any idea where I might procure a reasonable substitute if the one I have is not suitable?

Thanks for your help.

Don
