1980 Firepower
My "ball ramp thrower" (sol. 08) is not working during game mode or solenoid test mode, but the solenoid will fire when I ground Q29 driving that coil. I just replaced Q29 (visibly blown and tested open), but I suspect that the 2N4401 could be bad as well. One of the outer legs measured around 0.225 with my DDM on diode setting (granted, this was in circuit).
I don't have a 2N4401 in stock. Will a 2N4403 or a 2N5401 work as a substitute?
Thanks!
