116B-121 Output Transformer Replacement
#1

I am restoring an early 116B-121. In this radio the push-pull output consists of two 42's. The primary winding of the OPT is open and I am looking at possible replacements. The Hammond 125D looks like a good option. If I were to go with the 125D, secondary lugs 4&5 seem to me to be the correct choice to properly match impedance. Please let me know if I have selected the right Hammond replacement OPT, and proper secondary lug choice.
