"...I am wondering what difference in efficiency there would be using the
Toroidal unit in place of an EI cored transformer voltage doubled such
as used in the Heathkit SB220 and other moderately rated amplifiers
Dentron etc.."

Aren't the original transformers at least 95% efficient? That doesn't leave 
much for you to improve upon, unless the toroid has gain!
