Hello Mark, I know this is an old thread, but I just found an identical "Senator" unit in *immaculate* shape for $50 and I'm wondering whether I should buy it... did you ever figure out what the cabinet's made of (solid teak, mahogany veneer etc)?
The electronics are definitely SS, so not much interest there, but if the cabinet is solid wood then I might pick it up and try to do some tasteful retrofitting. This thing is a real beauty, but it's absolutely *ENORMOUS* so I want to be sure it's worth it... before taking on yet another project.

Any info or tips would be much appreciated!
Robert.
