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

The DC resistance of the primary winding of a mains transformer will be low. It's the inductance of the winding which impedes the flow of AC current through it. Were this not the case very large currents would flow and burn out the winding. That's what happens if an AC only set is connected to a DC supply.
