Murf;
Measure the resistance between the plat pin of each #42 tube and the center tap of the output transformer, they should be of the same resistance within about 5 to 10 ohms. Generally speaking if you are measuring a resistance between the plate pins on both output tubes then the transformer primary is good. It's very rare to have shorted turns on the primary of an output transformer, and even if there was some shorted turns the total resistance would be noticeably lower then it should be.
