12V Deep Cycle battery with Pure Sinewave inverter for tube amp?
Recently I purchased the largest 12v deep cycle battery that I could find. I also purchased a small 500 watt pure sine inverter. After connecting my El34 Single Ended to the inverter, the results were incredible. I was just curious what the community thought about this idea, comparitively to power conditioners and what not.
