So, to supply the bricks on the bench, would a variac
rated at 2.5A be OK? I am not sure I know how much current the bricks will draw at 20VAC,
and at what voltage the 2.5A rating is given. Otherwise, would this do the trick?

As a general rule, a variable transformer (Variac) can provide full rated current at any
output voltage. So a 2.5A unit can provide 2.5 A at 1V, 10V, 120V, etc. With a 20V
output, that is 50 VA (Watts, sort of).
