risk factors for cataracts?
anyone know what usage/storage conditions are most likely to accelerate cataracts?looks as if some mold is responsible but not in all cases.i just got a heathkit roundie that has been in a barn 20+ years with its original rca tube dated 2-63 and no sign of them.
i have opened up new tubes that were stored indoors and the faceplate was ready to fall off.
