I recently set up my Fathom using a reproduction Say-it-Again feedback/delay board from Parlor City Pinball and wanted to share this as I am very pleased by the results. With the board installed I am enjoying the added depth, atmosphere, and incidental variables to the original audio. MattHess (Parlor City Pinball) was kind enough to help me figure out the wiring and jumper correction to get this working properly. I would recommend adding Say-it-Again to almost any SS Bally that uses S & T audio.

I didn't realize that a Say-It-Again board could be made compatible with a Sound Plus/ Vocalizer. Thanks for the tip. I might have to try this on my Xenon too. Do you have any notes on the wiring/ jumpers that you could share?
