You've made a couple of mistakes. The interesting thing is that your two mistakes actually resulted in the correct answer; almost! ;-)The cartridge was rated at 0.25-mV. That equates to 0.00025-volts.
You can add decibel values, but you have to multiply actual gain values. Therefore, the total gain for the preamp would be 57.5-dB + 20-dB = 750 x 10 = 7500.
Preamp output voltage = 0.00025 x 7500 = 1.875-volts.
Good luck!
