Saif, I do not see any chance to successfully finish your project, without having a look at signals with a scope! You are totally blind without scope. And this where you build something that produces a dangerous voltage!
For 50Hz even the cheapest and poorest scope will help. But to design this circuit without scope is like driving a car with closed eyes.

I could not agree more.

One comment
yes, "For 50Hz even the cheapest and poorest scope will help", if you can borrow one, great. HOWEVER, if you go buy the "cheapest and poorest scope" you will be throwing money away, since that being good enough, for you next project, is a chance close to zero.

I do appreciate that not all developers have a nice tool budget, but doing what you do without a scope is "the blind leading the deaf"
