Laney LX120RTWIN

Hi,

This amp had its bridge rectifier and darlington power transistor STD03P blown. This transistor is obsolete. I have 3 pairs of SAP16P transistors and heard that they can be used as substitutes. As per datasheet, the STD03P does not have an inbuilt emitter resistor whereas the SAP16P has the inbuilt resistor. So If I replace it with the SAP16P, then, do I have to remove R14 and R21 from the circuit. Schematic attached, Please assist.

Thanks
