Just got a new portaflex pf500 and 115 cabinet. Took it out of the box, played for about an hour when I heard clicking sounds. Next thing I knew the head was smoking and I has to yank the plug. I really like this setup but I have a bad taste in my mouth after the expierence. New head on its way but wanted to see if anyone had any comments in regards to my expierence. I'm nervous now.
