Has any one had issues with the HL-2K from THP - like acrking/vaporizing 
contacts on 75M....

Iv blown off the contacts again - as the plate loading was being decreased, 
power was still increasing - again around 900W the problem shows its self and 
im not sure why. I haven't opened the amp yet to verify that the 75M & 40M 
contacts are cooked - im just guessing an ark from the 40m to the 75M ...... 
because the contacts were new and no groove was seen in the sliding plate. Q to 
high?? mabey decrease the tank coil by one turn ..??
