[Vintage-Radio] Freed-Eisemann NR-7

[Larry WA9VRH]

Hi Alex,

Thanks for the information.

At least one question.
Is there a trick t getting the tubes out of their sockets? They all seem to 
be at a bit of an angle but I grunt and groan and I don't want to damage 
them. There are already a couple that will probably need replacing.

Thanks again for the information.
