42-321 Questions
#3

The field coil is measured between the two Plusses of #31 cap, can't see the value, looks like 530 Ohm, but should be under 1kOhm.

Terry gave you the measurement for the output xfmr primary.
The secondary is always fine.

Now the speaker itself is another matter: you cannot measure it unless unsolder one of the two speaker leads,
then measure between them to see the resistance of maybe 4 or 8 Ohms. Otherwise it is masked by the secondary low resistance.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
