The best advice I can give at this point is to review this schematic:   
      
   http://arcarc.xmission.com/PDF_Jukebox/Rockola/Schematics/1448.pdf   
      
   And make sure you have AC coming in from the power supply unit to the amp.   
   Check also the plug from the speaker as this will interrupt the primary of the   
   amp's power tran if not certain jumper pins are not making contact. This is   
   intended to keep the amp    
   from functioning if the speaker is not connected.
