Re: HA Issue

["Brad" <bsnedek@xxxxxxxxx>]

Thanks for the input guys,

   Just finished ordering the replacements. And I also found a X10
schmo for my scope. So I'll build that and of couse isolate my scope
ground and see what I can see.

   Dave, are there any off base harmonics that you know of I should
look for? Like multiples of 120khz. I do use Jeff Voltz XTB, Could it
be amplifying off base freqs?

   Well I guess anything is possible.

   Thanks for the help
    Brad
