Experimental transformer for use with MM cartridges with an internal impedance of around 500 Ohms. Nominal impedance ratio 10k/40k. DCR 1000/2000 Ohms. Provides 6dB of gain and ground isolation. Bandwidth limited but depends on cartridge and load impedance. Secondary needs to be connected to a high impedance input. Two transformers are required for stereo.
