    This module provides a high voltage for my models equipped with vacuum tubes. The module is miniaturized with easily accessible outputs. It is very practical. Beware of dangerous output voltages. The module generates interference which must be energetically filtered at the output and, if necessary, inserted into a perforated sheet metal case which will protect against high-frequency electromagnetic noise and any handling error. A capacitor charged with high voltage remains dangerous for a long time after having disconnected the power plug. Multiple voltage outputs on solder pads, ideal for models to be tested.

    I am very satisfied of this module, it works accordingly to the spec. Just some suggestions: 1) To switch on the circuit it is necessary to put a short between the K and SW pad on the PCB 2) don't trust to the AC Voltage measurement provided by the multi-meter, except it is a thru RMS device capable to work up to 20 to 30 KHz.. To make a correct measurement use the oscilloscope. I powered with 12V and found a 450V pp square wave at output with a 220V 60W lamp , it is much more than 220V rms, but it is ok, the running frequency is around 20KHz. The module can be used to power a tube amplifier. To transform the AC in DC you can use a fast rectifier and a capacitor, the 12V DC input can power the tube heaters and the converter itself.
