On the spkr plug you can measure any 2 pins against each other and you should have less than 3.7K. The fc is abt 3.2k and it's in series with the center tap of the output transformer. So it's in some combinations you could measure the fc + 1/2 of the output transformer's primary. If you measure a resistance like 10 or 20k + there is a problem.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
