Can I get the opinion of those more learned than me whether this hack I’ve just done is ok and not likely to break anything?
The lamp on my right spinner wasn’t working on my Future Spa. I identified the issue as the associated transistor and when I looked at it the area around it was a mess. I took it out but I think the holes are wrecked. I couldn’t even solder a new one in. I don’t have the skills to fix this.
So my hack idea was to tie the right spinner lamp to the left spinner lamp. They always come on together in this game, never separately. So if the spinners qualify for 1000 a spin, they both light up.
It seems to work great. Any potential issues?

I think the tiny Bally SCRs on the lamp board are only rated for 1 lamp. Use LED bulbs and you would probably be fine since LEDs draw less current. Use non-ghosting LEDs since there is some leakage current on the SCRs.

Thanks for that. For this one it’s the larger MCR106 which maybe is higher rated? I’ll give some LEDs a go anyway.

The larger MCR can handle 2

Hey there! Got a moment?
