I have a solidstate base amplifier here and I have no clue who makes it. It says GB 300 SOLIDSTATE Three Hundred Bi Linear. I has a 4 position power selector 3 rocker swtches preamp, am/ssb, power on/off The unit is a good size heavy and is black with red lettering the 4 power transistors are MRF-492 I may have to look again its been awhile.
There is a problem with it if I remember right the SWR was sky high on all power settings is it out of tune or where do I look?? Bad cap something on the input side?? Ide like to get this working Thanks .....Tony
