[b]DOES ANYONE KNOW WHAT WOULD REPLACE Q-501 FET AND IC-501 ON THE RECV IF/AUDIO/AGC BOARD THATS IN THE HEATHKIT SB-104 RADIO? I HAVE EXTREMLY LOW AUDIO YET ITS CLEAR. IVE CHECKED EVERYTHING THAT I CAN AND CLEANED ALL CONTROLS AND PLUGS. I SUSPECT THAT THE FET TRANSISTOR Q-501 IS BAD AND ALL I HAVE IS A HEATHKIT NUMBER.[/b]
