With the spare time at home, I have been playing on the bench. I built a '29 era transmitter from a 1934 QST. It uses a pair of #245 tubes in a push pull collpits design. It runs on 80 and 40 metres with a maximum of 3 watts output. The coils are wound from some heavy square copper wire that I think was for large transformer winding. Even the board is vintage, it was in the scrap heap in the old barn. It cleaned up in the planer. A very enjoyable project with lots of learning along the way.
