817
What is the part number for those OPTO COUPLER transistors? 817
I will use ETD 49, Do I need to modify any thing? Will I get the same power?
Thank You

At least 5mm is a must for isolation, between Primary side and secondary side. and some times Air Gap, like drilling the board.
Since I still need more information, Why we need that space, Because of Safety or Circuit performance?

Yes he is right! Good eyesmegajocke said:
There is no mains isolation for the output voltage feedback!
Smoke!
What you have is something that no one has, if you don't like insulation of feedback, then controller has to be on secondary side, and you will probably need to drive fets with trafo, like in PC supplys
also you created: secondary - output rail to be gnd of ic, and also you said that -65v will be gnd with that, so then 0 will be +65, and +65 will be another 65v higher, not really how you do things, if this would even work
