VR-1 is the varistor and that will have mains voltage on one of those broken legs. The large resistor is a 600-620 ohm 10 Watt resistor.
Was the varistor on the board before you started troubleshooting ?
As Ralph suggests, there could be a serious underlying issue that needs to be resolved before moving on.
I haven't done anything to that area and I got it like that. It has never really worked properly from the outset so it looks like I will to get a new rectifier?
Doesn't look that complicated - unlike the solenoid board that I resoldered the pins on. Maybe I can just get parts??
From this reply, it's evident you're confusing the solenoid driver board with the MOU board.
Like I said earlier, spend some time reading over that online manual. I've read it about a dozen times at least. It's a valuable source of good information. Please please get familiar with it, you will learn a lot from it. And to be honest, if you're going to own a pinny it's best you know how to fix things.
The new bright green board is the rottendog solenoid driver board, looks brand new so should not have any problems with it, but it might be worth checking the fuse on it isn't blown.
To repair the rectifier board you can get most parts from rtbb.com.au but you'll have to remove the board from the pinball which means snipping all the wires soldered to it so make sure you take some detailed notes!
I'll offer to do the work for you if you want but you'll need to send me the board and all the components.
