He joined the board in the late 1980s as a director and served as vice-chairman between 1989 and 1992.
He had stood down from the board after the arrival of Sir John Hall as chairman.
Mr Mallinger, who served as non-league Kettering Town chairman between 2000 and 2005 and later as chairman at Corby Town, died in hospital on Friday.
