Note in the ad, Sansui writes that you can TOUCH it if you want to, but nothing is mentioned about LIFTING it Thats entirely understandable, the last thing the company needs is a potential customer trying to lift it in the store and getting a hernia or going into cardiac arrest, and Sansui gets served with a lawsuit
(unless the customer's name happens to be Mr. Schwarzenegger, as in Ah-nold, ze Govenah of Calee4neeah) though he was a mere unknown back in late '75 when the BA-5000 was unleashed onto the unsuspecting audio world.
