Does anybody have or know where I may find a schematic for this radio? Its a Hotpoint Bandmaster wooden egg crate, not sure what actual model, but valve lineup as follows 6A8G, 6G8G, 6V6G, 5Y3G.

The 6G8G is missing and I can only get hold of a 6B8G, apparently they are interchangeable?

Model C64ME from 1941 uses that valve lineup, circuit is available from:-

http://www.radiomuseum.org/r/austral_ge_hotpoint_bandmaster_c64me.html

That same site lists those valves as "normally replaceable - slightly different"

Thank you JFB I have found and downloaded it, dismayed as I now need to find a 5" 1000 ohm field coil speaker... A bit like rocking horse shit no doubt, although I'll pull it apart and check for sure as I have the radio minus the speaker.

I do hope it is realised, that for some of those SE audio transformers of the open type, albeit that there are ways of extracting the ISO ones that are in a can full of tar (no feathers), you can knock it a part & fit a new bobbin.
