Star Wars Data East, 1992

All switches test ok.
Signal is not reaching destination.
Already replaced ic 7408.

Looking for:
ra26 resistor array 2.7k x8
ra10 resistor array 560ohms x8

Anyone know where I can find these resistor arrays?

Try mouser.
Have you done continuity checks to find the break? Don't want to just guess.
I had to add solder to two transistors that were replaced by someone previously that were simply not making contact at the pcb.

Thanks stangbat... I looked but couldn't find the 8 pin versions on that page. Any other locations that might have them?

Actually... I was *told* to find:

ra26 resistor array 2.7k x8
ra10 resistor array 560ohms x8

In the ball launcher line up to the 7408... are these specs correct for what I should be looking for?

I should also say that I do know that if we manually trip it at the 7408 the ball shoots right out.

Any help finding these two parts please?

ra10 resistor array 560ohms x8

GPE has both the values you need in 10 pin versions. They are bussed resistors, cut off the two pins you don't need. Cut them off the end that doesn't have the black dot.

Thanks Stangbat!!!! : )
