Philco 84 Ant, Osc, IF, Power Transformer valiues.
#3

Don't think there are any rf/if parts on the 60 that are interchangeable w/the 84. Both osc coils are prone the have bad primaries so it makes sense to rewind the proper one. The 60 is a two band set where the 84 is a mono band set. There's no feedback tap on the (60) IF transformer so the original regeneration circuit won't work.

Generally speaking all of the rf/if coils should read <100 ohms, opt 400 ohms, and hv secondary 600 ohms end to end. Bear in mind these are all rough numbers. The true test is the measure the ac voltage from the ct to each end and it should be pretty equal +/- a couple of volts. Anything that measures in the 1000's of ohms is bad/open.

figure out what all those squiggly meant.
