[QUOTE="Steerpike, post: 196760, member: 807"] Any photographs of it ? Is it all valves, or just the line output stages (which were the last to go solid state). I think several Philips' had ICs even for signal processing in the early 70s, it was just the HV area where they kept the valves by that time. I don't think anyone ever made a PAL colour decoder with valves. Our SIF is 6.0MHz (same as UK), but it would be possible to change that, I suspect maybe without even changing components - depending on how much variation the coils will allow. [/QUOTE]
