My KPA 500 has been running ok for several years on 120 Volts. Today I turned it off on the back , unplugged it and opened the top because I thought I might need to change the voltage tap. I did not need to change it. I replaced the top cover, plugged it in and turned it on at the back. All ok, but when I turned it on with the front panel button the HV reads .1 in standby. If I tap OPER it shows a hard fault and "270V error" .The Manual says this is a 270V supply failure and to recycle the mains power KPA 500 after it is corrected. I tried recycling the power but still faults. I don't have any 270V power from the mains, if I did it would be 240ish, not 270. The fuse block on the back is set to 115V.Any advice would be welcome.Mike, WM5DX.
