"D40K1 - cant find this anywhere. Google implies its a Darlington Power transistor, possibly NPN. What can I upgrade this with?"I don't know about upgrading, a lot depends on how it's used in circuit. But if you need a replacement this guy has single pieces:

I'm not related in any way to him.
Be careful about "improving" transistors. Sometimes that hot, fast, high Ft new number looks great on paper but ends up turning your amp into a high frequency oscillator! The D40K1 is pretty non-glamorous, it was used in things like doorbell chime driver circuits. But it is reliable and cheap.
