Hi Brooke,
When I do the math, I get:
P = (1V)^2 / 50 = 20mw
and
P = (5V)^2 / 600 = 42mw
The power is there, so therefore, so is the voltage with the
correct transformer.
Or, another way, remembering that the ratio of the impedances
is the square of the turns ratio:
600/50 = 12:1 impedance, therefore we need a transformer
that has a SQRT(12) : 1 turns ratio, which is about 4:1
