[Amps] Thp HL-2k

[MIKE DURKIN]

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 ..??
