Tucker Tin schematic here on my web site:http://www.karinya.net/g3txq/temp/tucker_tin_sch.png
Sorry about the quality - it's from a very poor photocopy I have.
You might also be interested in the 3-tube "Imp" SSB transmitter that appeared in the May 1960 edition of QST magazine. The extra tube means you don't need the carbon mic, and it used a separate VXO so you had some frequency agility.
I also have the schematic for the Tucker Tin Mk2, but that used a number of semiconductors on several PCBs and is nothing like as simple.
