Wonder that myself. Worth what someone's willing to pay for it but... I personally in 2024, have paid upwards of $250.00 for a decent non working SA-1000. Depends on condition.
Just brought back to life my SA-1200 4 channel Bi Amp system. Also a SA-450, needed capacitors. Both are fully functional in 2024 after decades in a BOX.

yeah, sorry, I refer to the AUDIOMOBILE company that ran from 1975 till 1988... In 2024 AUDIOMOBILE is a different company and they primarily make speakers and interfaces. BDBD/2024
