    1. trace the circuit to determine if npn or pnp then given the spec of the driver (2.5A, 24v IIRC) choose something appropriate in a modern transistor (6 - 10A Ice-max, Vce 100v+, which is likely to be better anyway on Vce-sat and hfe specs). TBH, given other things have may have died I'd not bother.

    2. buy a replacement driver off ebay (or check if members such as JohnS have some left over from upgrades)

    3. use this as opportunity to upgrade to modern drivers
    It seems I do not have choices here. So I better follow your advise irving but for upgrading I do not have a plan yet. And I think I know of at least one way to test this part off the pcb and see if it is a PNP or NPN.
    Thanks.

    cheers
