Bench testing the beast…

Joyful mess

On the left is the power supply area, two 2100v microwave oven transformers, a 12v 12A heater transformer, level shifter diodes, capacitors and one of the control variacs. Bottom right hand corner shows the oscillator unit, top right hand is the primary and secondary coils. In the middle is the main tube, tank capacitors, filter capacitors and power meters for plate volts and current and screen-grid volts and current. This birds-nest lash-up is easily capable of putting out enough power to kill so it has to be treated with the utmost respect, you really will only get one chance when mucking with this sort of power!! Then there is the fire risk and so-on, it’s not a past-time to be taken lightly.
