Help with PLL

Hi,
I have decided to build an induction heater using PLL (Link2 This schematic uses the 4046, but I only have the LM565. Is it possible to modify the schematic to allow me to use the 565 instead? (Sorry, I am relatively new to all this stuff)

It should be possible, as the original is using the Type 1 phase detector, which is what the 565 has.

Can someone check to make sure everything is right?
