Description
This is a module of a circuit that I have used successfully in another project.
it is a High Voltage Generator, based on the MC34063 IC .
It developes a high-voltage, low amperage output from a +12vdc input, using a buck-boost topology with an Inductor and fast-switching mosfet transistor.
I have used this same circuit to provide high-voltage to the Plate of a vacuum-tube preamp circuit (12AX7/ECC83).
Adjusting trimmer resistor TR1, sets the high-voltage output.
It is important NOT to exceed the voltage ratings of Capacitors C1, C2, C5 or the recommended Plate Voltage of the vacuum tube.
I normally set the output voltage at +250vDC for the 12AX7/ECC83.
*WARNING: SHOCK HAZARD*
Although I have used this same circuit successfully, this layout is currently Unverified.
