The phono gain without the cascode is about 45 dB. Works nice with 5mV.
Pay attention to loading of the output of the SUT. If its designed for your cartridge the stock load of the preamp (47K) is probably fine. But if its not intended specifically for your cartridge, there may be additional loading needed. The loading strip on the MP-3 might be handy for this. If you change cartridges, the loading of the transformer will change with it. If you are running an SUT like this (for example, a Jensen) the loading will be a resistor and capacitor network (Jensen has suggested values for all known cartridges on their website).
