Repair Electro Industries 3002A PSU after reverse polarity

I carelessly attached a battery with reverse polarity to my Electro Industries 3002A PSU. I didn't realise until I saw a wisp of smoke after maybe 10 seconds. Needless to say it now does not work correctly. Looking inside the circuit board is populated with easily accessible discrete components that I could probably replace. So question is what is likely to need renewing? I assume active devices such as 2N3055, TIP31C, L7805CV. What about passives eg capacitors, resistors? Appreciate any advice before I condemn to the bin.

Check to see if you just smoked a diode on the input.

Get your nose right on the circuit board - you should be able to sniff out the burnt component.

thanks. Will apply olfactory analysis. Hope repair is a simple as that.
