1 - DISCHARGE HV SAFELY and MEASURE TO MAKE SURE THERE IS NO VOLTAGE ON
THE PLATE SUPPLY
2 - remove the tubes
3 - power AMP up again
4 - check Ip again if Ip == 0 then the tubes are probably at fault most
likely a grid to plate short
5 - If you are still seeing current check the ammeter circuit and the
plate chokes
