Hi after reading about the panasonic tau tubes being put in to the Philips 9617, I decided to give Philips a ring and find out their version. Apparently, so the guy says, only the 9607 contains the cyber tube. The 9617 and 9527 use the Panny. He did stress that although Panasonic make the tubes they are made to specific Philips specifications and that Panasonic only manafacture them. I think this guy had answered this question before,as he was ready with answers. He also stressed that there is no difference in peformance and that it is no secret that manufacturers share parts. When I asked if any future sets would contain the cyber tube, he replied with a "dont think so" So, does anyone else know any different? Will we see the Cyber tube again? Is it superior? Do you think he was fibbing?
