A viewer reached out and inquired on which of the six terminals to attach a 8 ohm speaker. In this case, there was no accompanying documentation for the SNC, 6P167 universal output transformer, so a simple M&P I'm sharing allows us to back into the selection by knowing the load resistance of the particular output tube(s), using an audio signal generator to generate a sinewave (600 Hz to 1 kHz), a high impedance VOM (or O-scope) and some simple math to determine the turns ratio and reflected impedance. Hope this helps Steve and others.
Thanks for watching and subscribing to my channel on vintage radio repair and other related circuits.
