Default Re: Help identifying 1920s 1930s battery set

You can use headphones, they'll be live (a nip rather than dangerous) and should be connected the right way round to aid what magnetism is left, rather than oppose it.
It's in good condition, many have suffered decades of lofts or worse. The screen grid valve looks to have lost some of it's getter, but may still be OK. There is a lot of information on the internet, and there were relatively few variations on circuitry, so it should be possible to restore it to health. Surprisingly for a near 100 year old radio spares are easier to obtain than many modern ones.
