Less than 1 year old perfect condition and sounds great. Musical Surroundings Nova Phonomena phono stage! The battery pack in the power supply of the Nova is self charging; these “smart” batteries disconnect from the circuit when charging and they self-charge if the unit goes unused for a week. That’s pretty smart! Two, seven cell NiMH “AA” packs, one for each positive and negative power supply are charged separately in case there is different current usage between the power supplies. This fully dual mono, discrete circuit phonostage can drive any cartridge; gain is adjustable from 40-60dB and loading is fully adjustable from 30 Ohms to 100k Ohms!
