Steam Resonator (Memo WFC 423-DA)

The PCB replica is provided below. All components are through-hole (THT) in this revision. Unfortunately, the winding ratios aren't provided in the WFC 423-DA. Experimentation will be required. 
A circuit analysis document will be coming a later date.

CD4046 (Phase Lock Loop) Based Gated Frequency Generator

NOTE FROM ETHAN CROWDER: This is a simple square wave oscillator, with close to a fixed 50% duty cycle, that utilizes two CD4046 Phase Lock Loop ICs. Four potentiometer connections have been included for each IC, that allows very precise frequency control. I've use four 10-Turn precision potentiometers. The CD4046's are supplied 12V. This was chosen for easier integration with more modern N-CH MOSFETS, which typically require a gate voltage of 10V minimum for full turn on.
