I have a large, heavy freestanding PSU for a linear that never got built.
I was intending a large singleband linear with two GS35s, but never got the RF deck built, and probably will never get it done.
This HV PSU puts out 1.0A continuous at 4kV. It has protection circuits and a voltmeter, and outlet is an HV coaxial socket, Its big and heavy, and sits of a trolley of 4 wheels. Its about 600x600mm x about a meter high (on the trolley). Fully enclosed steel casing.
Anyone interested?
