and so the project begins. The variac is a requirement. Oz Hams ARE restricted to 150Watts input. | will all the bits actually fit in the designated box ? | this is the power transformer. It is on wheels. Its big, real big. 1.4KV 4A secondary . Seriously ? It was free. |

you cannot control that which you cannot measure. The PSU will labor in a remote and dusty corner. This will be the control head. | this was a little hand drawn PCB to house the 3A 1000V diodes. The tube of resistors will be a voltage meter dropper. MOV string to protect the diodes | the PSU will be power inrush sequenced to provide orderly startup and remote emergency/fault shutdown |

I have been saving these large 200V electros for years for just this | this stack gives me about 24UF at 2.4KV | was this the inspiration ? Maybe. Oz VK Hams will get 1Kw privileges.. One day. |
