The amp in question is a 2 x 2879s Skipper by Palomar box AB-1 (mobile) everthing works on the box except the High and Max side of the box ? With 1 watt DK to 18 watts pep on AM , Low does about 10 to 40 and medium does 15 to 60 , and does the same on SSB . The numbers only change very slighty, if any, on High and Max but it still shows major amp draw on those two settings ? The amp looks very clean within (for what good that helps me,although the screws on one of the 239s look longer then the others so it's obvious to me that somebody was in there before ? ) Could 1 Transistor be bad on this or could it be something else ? Anything I could look at on this one ?
