I have an Amp here its a 110 AC Base Amp its kind of a Palomar Style it says GB on the front with a 4 position power setting knob. What it has for Final Transistors is 4 / MRF-492. The problem is no matter what radio I have inline the SWR is sky rocket high it belongs to a friend and it was doing this for him aswell what would cause this out of tune Biasing?? Where do I start its a mind boggling problem
