Hey guys.

I’m going to replace the rectifier board in my EBD and see at least two different types out there.

The Rottendog board

And this one.

Sorry if this has been brought up previously. I see the Rottendog one is redesigned with only one bridge. The other one looks like a clone of the original..

Are these the only two choices. Is there a clear reason why one is better then the other. One is available new off eBay for 80 plus 6 in shipping

Thanks

Dave

What's the reason you want to replace it?

If I had to choose between the two, I'd go with the Marcos unit.
It has an extra fuse for the General Illumination circuit so there are two - one fuse for the playfield, the other for the backbox.
The 620 ohm resistor used is rated to 15 watts compared to the 10 watt part on the Rottendog.
It's using two 35 amp bridge rectifiers as per Bally spec. With any luck they might be positioned in the original location Bally designed them to and maybe they can be mounted underneath the PCB to take advantage of the large metal baseplate as a heatsink. The bridge rectifier running the switched illumination circuit will otherwise get quite hot if you're running incandescent lamps.

Thank you quench. Sounds like the Marco is a better choice.

I am trying to decide if I will rebuild the existing. At least I know which direction to go with a new one if I do.
