Thanks for the responses Gary and Bob. I'm a little surprised that there's no back panel - although I know older Philco's were that way. There's a slot in the cabinet at the rear that looks like it could be used to attach a panel - I may make something up to keep hands out.

I was lucky that I got the radio with an operational FM1000 tube - albeit rolling around in the back. The FM discriminator is working pretty well but it's a picky circuit to get to that point. I think my strategy would be to adapt the radio to something else (6BN6?) if the present FM1000 failed.

Many thanks!
