Thanks very much all. I now have a project for tomorrow.
It's a nice little set, purchased from the oft mentioned NY TV dealer Vaughn about 15 years ago. Packed in storage for the past 5 years. Unfortunately today I broke a 6SN7GTB when it rolled off the table.

Ordered a couple of replacements today.
Anyone have experience using this set with a DVD or VCR? When I hooked it up briefly last night to an RF modulator the set went nuts with wavy lines (almost like vertical sine waves) on every channel.
