[Jukebox-list] rockola 1448 Amp question

Hi all , is there supposed to be a power resistor betwwen pins 2 and 5  of the speaker female plug on the amp?  Miine has one , the brown sandy kind, thats reading about 12 meg ohms. The schematic just shows a straight wire between 2 and 5  . 2 goes to ground.  Thanks, Jim
