This source says the 82090B contains just a simple transformer that delivers 9 V AC. Nominally, that is.

However, I'd be very careful with a different AC adapter, even if it has the same nominal rating. Maybe someone can measure the 82090B's open circuit voltage as well as the effective output voltage while the batteries are charged. Maybe even someone can provide the charging current.
