Hackshop Lafayette update: Balance (sorta) restored reveals CRISPY module

In the previous video (   • Dungeon Hackshop: borked Lafayette LR-5555...  ) I introduced the Lafayette LR-5555 receiver and its apparent faults. I since replaced a broken part with a diagnostic equivalent, allowing me to find other faults and confirm suspicions. Unfortunately, those confirmed some relatively pricey needs. But what if there's a cheaper (I won't say better) way?
