I have posted a simulation for investigating energy dissipation when a high power transmitting vacuum tube arcs over from anode to grid (A-G arcing). I have simulated energy dissipation in the glitch resistor, in a simulated SCR based crowbar circuit and finally in the vacuum tube itself. In this case an Eimac YC-179 high power [...]

I have posted the equivalent schematic for my hipot tester. The design is based loosely on some ideas from K8CU and AG6K. However, I have simplified the circuit somewhat and used different components. The mechanical encapsulation is also different. I used LTspice to verify the tester before building it. The schematic is from the LTspice [...]

I have posted some pictures of the hi pot test setup of my new Eimac YC-179 vacuum tube (MRI pull). This is for a future legal limit (LA amateur regulations) amplifier for digimode and contest CCS amateur radio use. It is better to run a tube cool than to stress a smaller tube for high [...]

I have been working on a new HI-POT tester ( high voltage tester) for checking breakdown voltage of vacuum tubes, RF vacuum capacitors, HV cables, RF relays etc. You can check out the comprehensive photo gallery:here
