Blown Valve Amplifier -(:

Posted by highfell on November 25, 2016 at 13:46:51:
I swapped my GEC KT88s over in my Fatman 201 amp this morning. In doing so I must have jerked one of them too hard because I now known one of the valves to have a slight rattle, which I remember hearing after I had pulled it out.

Anyway, I realised something was wrong when the sound died in one speaker and I smelt burning. When I went to the amp it had smoke coming form the bottom of the valve. Switched if off and pulled the faulty valve out which was super hot.

Let everything cool down and put in cheap Chinese valves. The amp turned on, the valves all lit up BUT no sound ...........

Any thoughts on what could the trouble be ........I guess impossible to tell.

Off to a local hi if repair shop ........
