My Sansui TU-517 came with the rack handles but it doesn't have the backstands. I guess both were options when the tuner was new. The TU-717 cabinet looks like it might be the same dimensions as the TU-517. I was wondering if the TU-517 and TU-717 used the same backstands and if they did what the model number of the backstands was. I measured the two backstand screw holes on the TU-517 cabinet and they measure roughly 3 and 3/4 inches apart on center of the holes. Any info would be greatly appreciated since I'm trying to find a pair that will fit.
