The calculation

n = Nsecondary / Nprimary
Gain = 20 log₁₀(n)
Rreflected = Rload / n²
Vout = Vin × n × Rreflected / (Rsource + Rreflected)

Assumptions & limits

Ideal transformer and resistive source/load at the specified frequency. Winding losses, inductance, capacitance, bandwidth and phono-stage overload are excluded.
