ECO #391 AND ECO #394
REPLACED R75 WITH D47 SO +12 IS NOT DRAGGED DOWN
BY BATTERY SUPPLY WHILE C27 DISCHARGES RAPIDLY AT
WHEN UNIT IS TURNED OFF. THIS PREVENTS UV LOCKOUT
ON IC7, WHICH CAUSES IT TO PUT OUT DC.
ECO #412 AND ECO #413
Q10 BSS100’S HAD STATIC PROBLEMS ON ASSEMBLY LINE.
Q10A BUZ71 IS USED INSTEAD.
ECO #415
ADDED C49=.01uF TO PREVENT IC7 "HICCUP" DUE TO
NOISE ON +5 DURING RELAY SWITCHING.
