Your set was sold as a 1969 model with what Magnavox called Total Automatic Color. It was Magnavox's attempt to lessen the need to keep adjusting the tint control, (sorta worked) but I though it caused people to look kinda orange especially if the TAC switch was pushed all the way to the second position. The set uses the T-940 chassis which is in Sams 1141. I serviced an awful lot of those sets in the 70's, they're good sets but do have a few quirks. Take a look inside of the HV cage and look at the HV rectifier socket # 1 it should have a 3CU3 in it instead of a 3A3, we had problems with the 3A3's filiment dropping and shorting destroying the flyback, then between the socket and the back of the cage there should be a teflon plastic sheet, early runs tended to arc through the rectifier socket to the case and we were supposed to put in the teflon whenever we serviced them, later runs came from the factory with the teflon insulating plastic, make sure it has the heavier wire for the HV rectifier winding, should be a red wire with a couple of turns around the bottom of the flyback, the thin stuff they used tended to break down and arc through, simple problem just get heavier wire and rewind it, if it was turned off before real damage was done. If you have a problem with low contrast it's usually the 1st video tube which is the last tube on the right of the IF board, early runs used a 6LM8 but I can't remember what the later runs used. If you raise the chassis and notice a blob or two of tar that came out of the power transformer don't worry too much about it, they tended to dribble a little in the first month or so of operation, I can't remember ever having to replace a power transformer in one of these sets.
