Thanks everyone!
Ed, it is a model 17D17R. A copy of the sam's would be great. I think the lin. pot may be open...I can get linearity almost perfect, then it jumps to a distorted mode and stays there the rest of the rotation.
Sorry Marco-nix, I don't speak a word of french. I know enough Japanese that I could probably do some half way convincing TV babble in that language, and I remember enough Spanish to ask how to get to the bathroom, but I don't know phoque about French.
The plastic seems fairly sturdy compared to some I've seen from the same time period.
I'm definitely going to treasure this set...I was planning to bid on a green dualette on ebay earlier this week, but it went for close to double what mine did and it was missing it's antenna and channel knob, not to mention the power 'knob' was off of it so it's connection fingers may have been damaged.
