I bid you luck man, I have only ever seen one of them, and it was the 33,000, and it didnt work unfortunately, but god damn was it beautiful, the knobs are as big as my whole palm. If you really want to get big and bad you gotta get the CA-3000 and BA-3000, they are masterpieces. Allegedly the Technics SA-1000 was the biggest and baddest though as far as wattage, nothing compares to a XX,000 series for shelf space though.
The SX-1050, I almost hate telling this story, but I literally walked outside my house and across the street to the neighbors yard sale and it was sitting there. $10. I walked it back home and came in and nearly broke out in a fit of laughter, my wife saw the receiver and immediately knew what happened, lolol.
