Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, does everything work except no sound?

Is the Bose equalizer powered on?

Are connections / cables between Bose and Technics checked? ...good ?

Still, let's review the basics. Proposed preliminary checks (if have not been done) :

  • • try to plug in a pair of headphones;
  • • exercise speaker main/remote buttons;
  • • exercise tape 1 and tape 2 buttons;
  • • muting switch off;
  • • check Bose TAPE button setting.
