I posted this issue in the Quicksilver thread and Flynnyflacon was kind enough to respond he had a similar issue and it turned out to be some chips on the sound board. I recently just finished converting a Quicksilver that fast Eddie just picked up this morning. When playing the last game before breakdown I hit all the quicksilver letters and let the ball drain to enjoy the QS special bonus. To my horror there was no Qs bonus light and sound show before and after the bonus countdown?! I went and checked my game downstairs that's all original and there was no QS special light and sound show either. I know that my game has played it before so it's not in the settings because I haven't changed anything on the settings. The restoration has a brand new weebly mpu and my game downstairs has the original mpu. I would have thought the mpu would be controlling the QS special bonus and you would see the light show but not hear it if the soundboard is bad. Has anyone else experienced losing their QS special bonus?

Thanks dothedoo, it's great when there is nothing wrong with the game just my brain. I forgot that the 5x bonus had to be achieved as well as earning all the letters. Took the glass off, made the special and enjoyed the lightshow.
