By the way, do you want to DIY the circuit?

2019-11-12 00:12:01 Thanks but in this link there is any circuit board that has TP5551 op-amp . unfortunately i can not find this op-amp.

1)i can not find TP5551 in my place then can i replacement by OP177GP or AD623AN or OP77GP or AD8572ARZ ? if i can do it then which of them is the best ?

2)If i can replacement TP5551 by another op-amp , is need change in circuit board or only i can replace without any change ?

3) if these op-amps ( OP177GP or AD623AN or OP77GP or AD8572ARZ ) are not the best choices please tell me your offer.
