So I have been looking for a proper genuine one that doesn't cost a Kidney for a Bally 35 Driver Board.
Pic 1: I bought some LM323K - ALL DEAD (last pic as well)
Pic 2: Bought some LM78H05 - They regulated on the bench. Put them on the board and they blew immediately! Not shut down but blown as when you put them back on the bench power supply no output anymore! So these "work" if in a 100% working board but if there is an issue/repair you are doing they just blow rather than shutdown self protection which the originals do. Pretty useless when fault finding a board!
Pic3: More / different batch LM323K and again all dead out of the packet!
Aliexpress purchases... got refunded but still looking for a good part.
Anyone have a good source in the UK that won't cost my Kidney???
