Hello, with the help of some members on pinside, I have been able to trouble shoot why some of my lights on my BW playfield were staying illuminated even though they are not supposed to. There is a bad transistor on the cpu board. It says it is a TIP122 but I was told I could double up and use a TIP102. I have some other transistors in my electrical box that I inherited from my older brother when he passed away last year. They have the following writing on them. I am just wondering if I could use any of these in place of the TIP122 or TIP102. Also I have a transistor on the SSFB which controls the 8 volts for the flipper hold. It should be replaced as one of the legs broke short. It says s660 B3 on it.
I have several of the following transistors in my toolbox and was wondering if they would work or maybe they are the same as what I need to replace, just they are labeled differently?
One says 7805c than 94 in the bottom left corner and 2 to the 4th power on the right (or 24 not sure)
another chip I have says s106b1 at the top, and 96 b in the middle
Another one says vortex lm317t than 6446e below it.
