Quoted from Wisker:... located the transistor for 3 of them which used the 2n560 transistor and one used the MCR 106 transistor ... So it seems that the new 2n560-730 has different input and output leg. Is that correct do they make more than one 2n560 is might be my issue?
Hi,
Are you sure, that your components are the right ones ?
The driver board doesn't use transistors but thyristors (SCR - PNPN). The board use both 2N5060 and MCR 106, depending on the power needed (2N5060 can drive about 1A, and MCR 106 cand drive about 4A).
For the MCR 106, OK, it's a TO-225AA case, the new component works.

For the 2N5060, the case is a TO-92, and there is no pining variation.
facing the flat side, from left to righ, you have Cathode, Gate and Anode.

Be sure that your component is not a 2N560 transistor ! this one has a similar case, but it's a transistor (NPN), not a thyristor (NPNP).
The 2N560 can't replace the 2N5060 !
