Output transformer for Philco 39-17
05-06-2016, 01:51 PM
You know it seems Philco speaker voice coils are commonly low in impedance. I just repaired a model 650 where the voice coil was 1.1 as it was written on the Nostalgia air scan of the schematics. A model 39-40 I worked on has the voice coil impedance at .25 ohms. Might that low impedance contribute to the primary opening up?
