Well moving on form the power supply, I would now like be able to turn the regulators off electronically which can be done via the the 1st CCT.

Now tried to use the Bistable Flip Flop to pull the Adjust down to ground but the Flip Flop does not turn fully on or fully off it's either partially on or off, can someone sugest a CCT that would be able to turn the grounding transistor fully on or off?

Oh and without using logic CCT cause i have a limited budget and will be useing spare parts and salvaged parts
