I think the easiest thing to do would be find a 50W~60W transmitter in either a late 40's or early to mid- 50's handbook. They would have the schematic, parts lists, and details of the rig. You could use either the ARRgghhL handbook or the Editor's & Engineers. Either one will probably have what you want. Mod-U-Lator, Mike(y) W3SLK
