  • "OOPS!" moment of the week.

    So, what was everyone's oops moment this week?

    I'll start er off.

    Working on converting a Laney AOR to a JCM800. got everything installed (new board from Metro) and was testing... a few little hiccups later,and I am getting proper B+.

    I turn itup a bit to test it out and it is getting wierd blocking distortion. It seems a little independant of the cable as well. I turn around to go and check for another cable, thinking my test cable might be iffy, when i turn back i see whisps of smoke! I think "Dang there goes a cap or 2" and go around the back of the chassis to turn it off. when i notice the output tubes glowing CHERRY! baking the logos on the tubes.

    Morale of the story? When you unhook the Bias supply to find a bug, remember to hook it back up again.

    Had to head home right after... guess i'll have a report on Monday!

    Whenever an amp sounds too good, check for red plating.
