Default Re: Aga Baltic AH37. Need help identifying old capacitor from 1930s radio

The chokes and output transformer are all good.

I read your post #1 again and it was working but the sound was very weak, so the mains transformer must be working, but the fault might be a problem with the speaker field coil.

You should be measuring the resistance of the field coil on the paxolin board connections between the chassis and the speaker (post #94 picture 3). It should be around 10K ohms. Corrosion on the terminals often makes it difficult to make proper contact with the meter probes.
