Oke so I put a extra 12ohm resistor in the power supply just in case, rather a bit lower voltage than too high. I've just measured our AC voltage from the wall socket and its running between 260V AC and 280V AC its supposed to be 230V AC . I think this might be what ruined them the AC going so high at nights sometimes its 300V AC, or I might have ruined them by drilling into the chassis while the tubes were still in their sockets coz I've red rough handling and shock can also make them microphobic stupid me I should maybe read some books on tubes or something. Damn I'm gona try 6N3P EV's this time now its a nother 3 months waiting and 2 weeks worth of beer money
