@surya:
thank you very much for the valuable suggestion. I very well know making is much easier thank asking and would really have appreciated if avinash sir had said the same thing instead of you

Regarding why I asked, For your knowledge, it makes use of PNP transistors for driving, NPN are only for switching the PNP transistors, i had already made my own (using 547+557) which worked fine, but was confused why avinash sir added power transistors thats why asked.

Thank you for suggestion and reply
