Quick question for someone with a Supersonic. I need to know if there is a post (or something else) behind the multiplier saucer (under the plastic) that would deflect the ball back into the saucer if it missed and tried to go under the plastic.

Mine had a mini-post there, but the PF drawing in the manual does not show anything in that area.

Thanks in advance -

that should help. Looks like a clear plastic lower piece (like also used on lost world) and a mini post.

Here is another view of the original design. It appears, here, they used a steel washer which I recall seeing on some other Bally EMs for ball deflection.

Andrew -

I circled the posts in the picture. They look to me like they are metal with a black rubber around them...I may have been confusing in the first post. I am not seeing the clear plastic lower piece...?image-4_circle.jpg

Cactus Jacks...

I see what you are describing. Would you think that metal-to-metal direct contact like that would cause issues? I want to be original but...

Yes, I agree. I wouldn't want metal on metal on a Solid State game. But its hard to tell from the SST pictures what might have been original. Hopefully, you can get a consensus from a number of SST owners as to what is actually on their games. But I fear its the kind of place where the post ultimately got ripped out from ball strikes and has been replaced with what was at hand at the time. Bally ultimately learned to use a ball snubber (bent metal plate) in later designs.

I knew I had seen the flat washer and post before. They used it on 4 Million BC in the Tar Pit - but obviously a low impact situation.

Mine looks like this.

Thanks cudabee....that seems to agree with cactusjacks as well. Wonder why nothing is shown on the PF assembly drawing in the manual.

Maybe we can continue to gather pics/opinions...

Thanks to all so far!

Mine looks just like cudabee's -- it's a wide post with a metal, penny-sized washer on the top.

Mine's the same, but it seems to be all one piece, so I guess they welded the washer to the post... no rubber at all on it.

I'm going over my buddies who has one tonight, I'll check his out

Thanks for checking everyone! Seems as though the majority have the bell cup bottom with the washer-esqe item on the top. I may go against convention and fit a ring as well...will post when I get it straight!
