Holy cow!
A community theatre up here brought two of these in one day looking for table stands and to be wired up to be used as props in a stage radio show....
I told them what they were worth, and they changed their mind quickly...
They were no where near complete as this, but gems like this are still out there somewhere hidden in places you don't expect.
Where did a community theater group find two 77-DX's......let me guess a neighborhood yard sale for $20!
