I've got a Hughes & Kettner Edition Blue 60 that sounds pretty good and used to work fine but it doesn't want to power on anymore. I have to either push and hold pressure on the power cord where it plugs into the amp which I could probably explain or I have to lean it forward at about a 30 degree angle which I can't explain. How hard is it to replace the power plug on the amp? I've tried different a/c cords so I know thats not the problem and I hate to junk a good sounding amp(although the celestrion and that extra peavy power amp would be a good start on a custom cab). Thanks
