My friend has a Lethal Weapon 3 and the shooter lane kicker stopped working. Looking at the CPU revealed that r80, q37 and the Tip122 were toasted. Being new at board repair, I,ve tried to figure out what exactly to order to replace them. So, I before I did, I wanted to confirm with Pinside that I'm reading the manual correctly.

So, I order a 2N4401 to replace Q37, right?
A Tip122, right?
And a 1/2 W resistor? But what ohms? And where on the schematic should I be able to find that info?
