The HV comes on with the power switch.

It sounds like a shorted tube, try one at a time or none.

If still broke there are other suggestions.

I have a sick Amp LK500-ZB and would welcome any advice and suggestions about how to get it back to life. The problem/symptom is when I turn the Amp on, within 1-2 seconds, the plate current shows approx. 300 ma, with no plate voltage applied. I suspected it might be a relay problem and ordered and installed a new relay...symptom exactly the same. Beyond that, I have not tried anything and that is my request for suggestions.
Thanks for your help.

PS: Last year I replaced the filter caps, Zener, plate choke and new 3-500ZG tubes. All worked well up until now.
