I have an X-Cel X-ray MB 700 A/C podiatry x-ray unit, which is having an issue of causing humming in the voltage stablizer, then causing the circuit breaker/power switch to trip. When the tube head is disconnected, this symptom disappears. The two possibilities that I have are either a faulty tube head assembly, (it's a 1994 model), or a shorted triac on the timer board. Has anyone else experienced this?
