Magnavox Astro-Sonic Sams Info?

I have an Astro Sonic console with television and having a heck of a time finding a Sams or any service docs. All the TV shops I hung around as a kid have closed up and the owners fled to florida. All I can get for solid identification is the model 2C7683 Run-6 serial unknown and all of the internal chassis tags have long turned to dust. Uses the 6JE6 on the horiz out and ultrasonic remote if that helps narrow it down. Set works well but has pincushion and horiz width problems being that its overscanning. HV is around 26KV.
Anyone help out with a Sams number? The earliest Sams catalog I can get is 1981 and doesn't show anything of a 2C7xxx number at all.

Hey anyone remember Marties TV service or Jensen TV in minneapolis?
