David, My *guess* is that the jumpers are to set the range of the horizontal scanning circuitry. Low would be for any horizontal frequence range between 15.5kHz and 18.5kHz and the high would be for horizontal frequencies between 18.5 and 23.5 kHz. In your case, you'd want the jumper on the low position. As to why you need an additional load on the composite sync line, there could be several reasons for that…if it works with an external load…I wouldn't worry about it. Don
