ONE Original Dynaco A-431 Ouput Transformer that was pulled from a working amplifier. NOTE: This transformer has P782 stamped on the cover. The gentleman that I purchased the amplifiers from stated that the original had gotten dented so he bought a used cover that was pulled from a power transformer. As you should be able to tell, the wiring is clearly an A431. I verified all of the windings just to ensure that it was 100%. Another output transformer from the matching amplifier will be listed separately.
