Hey all! I have a strange issue. I recently replaced the original backbox bulbs in #AmazonHunt with leds and took some of the working original bulbs to replace a few dead ones in the playfield. After i was done I went to play (obviously!) And here is what I discovered. There is now about a 10 second "lag" where no points will be scored. When it does catch up *most* triggers are registered. It seems they may be a limit to the buffer. I have simce removed all leds and returned to game to its previous state, but still have the "lag". Notable: the "lag" restarts every ball, and every player.

Amazon Hunt is a rare 1985 production, system 80a/80b Hybrid design

Any help/ideas/questions are welcome!

I am not sure. Is there a direction you could point me? For references/directions ?

Also, notable, Is there are already 3 leds that have been in the machine since I got several years ago. 2 in the backboard and 1 in the playfield

UPDATE: I took the glass off the playfield and triggered everything. After that, the lag has not happened again (3x games played)

I am hesitant to put the leds back in. And I did leave the 3 leds that were already present in.

Thanks, I will check out that link!
