I need a 750 ohm, 1% or 5% Tolerance, 1/2Watt Resistor to finish a Isolated 9V DC Supply.

Will trade for, or purchase out right.

have you not tried to combine more than 1 resistor to get the value you need ?
such as a 560 + 190 = 750
or use a small trim pot like a 1K and adjust it down to 750.

Make that a 1W pot if can't find a fixed 750 Ohm 1/2W because full length of resistive material inside the pot is not being used to dispate heat. Better yet a 2W pot because of current that will be flowing through the slider contact.
