I need to confirm the types of transistors which are needed on an early Bally SS solenoid driver board; specifically Centaur 2. The manual has the following descriptions:
Q22, Q23 2N3440
I currently have TIP 102 in stock but I suspect I will need to order others and I am not sure what I need to order. Additionally, I would like to order spares for all of my older (non Stern)games. Any help would be greatly appreciated.
