APEX nx400 watt MOSFET AMPLIFIER BOARD. DIY, pcb print mistake problem

in this video you will see a subscriber has purchased PCB from local PCB supplier of Apex audio board but during the editing of top Silk of this PCB the supplier has make stupid mistake by printing BC 547 in place of BC 557 .
so the subscriber was suffering from failure of the circuit and finally he sent me for finding the actual problem of this board

Sir in BJT amplifier board , instead of using 2sc5200 and 2sc1943 , can we use sanken 2SC6145A NPN and 2sa2223a PNP, will there be any issue , driver section C5198 and A1941 (Toshiba)

[@diamondaudio4994]

Last time when you powered the amp, I have noticed that speaker cone jumped up and down abnormally and also during the bass speaker cone was jumping slight abnormally Is that a circuit problem? Like bias problem.

[@AmplifierWorld]

It can cause due to unmatched or poor input transistor
