Regarding the color bars...the easiest way to adjust T703 3.58 oscillator coil (with color signal applied) is to short pin 2 of V703 (3.58 osc. tube) to ground and adjust for minimum number of stripes. Though circuit may need further work, you'll have the coil at a known good point.
You will find that several other terminal strips will need replacing and bunches of solder joints will need to be re-flowed. Reposition the power resistors while you are at it.
Though the resistor layout wasn't the best, it sure put a lot of bread on the table.
