Thank You Tom , I appreciate the help with the signal seek feature , I had the caddys with it , but most of my other , non GM cars back in those days were things like Mustangs and one really fast Road Runner . Go fast cars never had the luxury appointments like the pricier caddys and Lincolns had . As a funny aside , the white 61 in my photo had the auto dimming high beams and believe it or not the unit that reacted to the phototube's input had 2 vacuum tubes in it ! I know most folks know of the tube car radios , but to see tubes doing other functions like the auto dimming lights was a kinda cool discovery when I first opened the unit and saw the tubes . They had the "Guide" logo on them that you were discussing in your thread about your car . Congrats for it , BTW , I hope you get great service out of it .
And as to lubricating anything in these old car radios , I would do nothing without first speaking to the guy over at ARF who rebuilds classic car radios , I don't remember his name but he had an avatar of a 60's Tbird trunk full of old car radios ...
