The following documents reflect my current thinking on how the electrical part of the AZ-58 operates. If you see any errors in my theory, measurements or calculations, please let me know and I will make changes asap. I want to keep this website as my most current documentation on this work. AZ-58 RF Oscillator.pdf - AZ-58 RF Oscillator schematic. Typically you would also need a function generator, booster amplifier and phanotron plasma tube. AZ-58 Parts List.pdf - AZ-58 RF Oscillator with Phanotron parts list with approximate costs. AZ-58 RF Osc - V & Z.pdf - AZ-58 schematic with measured or calculated voltages and impedances around the circuit. 812 Tube Characteristic.pdf - 812 Transmitting Tube characteristic with the static load line (1100 VDC, 100 mADC) and dynamic load line. The dynamic load line is based on the real component of the circuit load impedance. This was measured in the Calc Circuit Z by Volt & Phase Meas.pdf document below. 4 inch Phanotron Equiv Ckt.pdf - Bill Cheb 4 inch diameter hand held phanotron equivalent circuit impedance. This is an average of the two measurement methods below Cal Circuit Z by Vari Cap Meas.pdf - This measurement technique allowed me to measure the basic components of the rf resonant circuit tank. My AZ-58 resonates with and without a plasma tube over the full tuning range of the variable capacitor. By knowing the capacitance at both ends of the tuning range and then measuring the frequencies, the inductance (L) and capacitance components of the resonant tank can be determined. The largest error is due to the variable capacitor values. Since it was already mounted and wired in, I took the average readings on eight samples of the same variable capacitor that I had in stock. The tank coil, resistance (Rw) and quality factor (Q = L/Rw) were determined using a "Coil Designer" program from www.qsl.net/k6mlo . It costs $15. From this method I could determine a value for the reactance component of the plasma tube, but not the real component. Calc Circuit Z by Volt & Phase Meas.pdf - This measurement technique allowed me to determine both the real and reactance components of the plasma tube. It also led me to believe that a significant portion of the resonant tank's capacitance is stray capacitance due to my component and wiring. I need to either change the layout or lessen the L3b coil turns from 6 to 5.5 or 5. The greatest error in this set of measurements is in accurately reading the phase differences in the voltages. Again I relied heavily on the "Coil Designer" program. AZ-58 SSS rf oscillator.pdf - This is a semi-solid state version of the 1958 Allied Industries machine. The mercury vapor rectifier tube circuit was replaced with solid state diodes in a full wave rectifier circuit. The rf oscillator/transmitting tube portion of the circuit is identical to that in the original machine. AZ-58 SSS RF Osc PL.pdf - This is the parts list for the semi-solid state version of the 1958 Allied Industries machine.
