UK Vintage Radio Repair and Restoration Discussion Forum - View Single Post - Aga Baltic AH37. Need help identifying old capacitor from 1930s radio

Mrgroovy · 18th Oct 2018, 8:42 am

I get impedance readings between 15-20 ohm between the two (three?) wires of the primary. This at least results in continuity/beeping sound on my multimeter. To put it in perspective, the resistance between two random points on the chassis is approximately 3 ohm. I'm not sure what readings should be expected. I've read a couple of other places that a power transformer with low resistance usually results in continuity on certain multimeters when measuring between the primary. I hope this is the case here because if the PT really is bad then I'm afraid I have no choice but to abandon this project.
