In fact you need to know the ratio, not the numbers of turns. Connect to the "Primary" 10 - 20V, 50Hz or 1000Hz and measure the voltage on the "Secondary". The ratio of the two voltages is the ratio of the windings. It's good to measure the inductance as well. It's up to the size and could be 1-10H. Higher - better basses.
