Working through this project has given me a new appreciation of the homebrewing skills of many of the hams during the twenties and thirties. The article on this particular transmitter has some gaps in the construction details....for coil turn information the builder is referred to the coil photo, to count the turns himself....and....Keying method is a reference to another chapter and, again, left to the builder to figure out.
I chose cathode keying for my version. I also buried the cathode resistors under the tuning capacitor. Keying added two additional Fahnestock clips along the left hand side. From the front mine lays out as keying (hot side), keying (ground side), filament, filament, B-/ground and B+.
