Q: 1pcb working f9. bt 2nd pcb supply(-30&ground) i reverse mistakeally & 470uf capa burnt out. pl guide which equipment s need to change with capacitor?

sir, please check the Fuse, Power Transistors , Driver Transistors and Resistors linked with them. if found faulty please change. for future proofing replace fuse Holders with 6A4 Diodes, so in case reversal of polarity the amp will not work.

Q: What is the minimum Output(Load) Impedance(ohm) of each circuit?

4 ohm minimum. 8 ohm recommended.

Q: You never mention the amp of ac transformer. is it ok to use 24-0-24 6amp transformer to generate dual dc supply for pcb? any modification required?

You can use 24 - 0 - 24 6 amp transformer . no modifications required.
