wstrickland1 Posted December 31, 2021 Share Posted December 31, 2021 If I could hear worth a darn I'd plug my system up to my EGO Powerstation and see if it made a difference. I have used it on an outdoor gig and it ran the PA perfectly Quote Link to comment Share on other sites More sharing options...

Battery may pre date wide spread electrification. Someone more informed than me will have to give you a complete answer Early vacuum tube (valve) radios ran off of batteries instead of house current. These antique radios required two different batteries for operation, an "A" and a "B" battery. Some models even required a third "C" battery supply. The "A" battery provided power to the tube filaments (typically 1.5 to 6 volts) and the "B" battery provided the plate voltage to the tubes. Unfortunately, vacuum tubes (with the exception of space charge tubes) require high plate voltages on the order of 90 V or higher to work. Back in the day, B-batteries were common place and relatively cheap. However, these large voltage sizes are no longer readily available, so an alternative is needed. Typically, radio enthusiasts power their radios using a special power supply that runs on house current. Though they work well, they are expensive to buy (or build) and they don't allow for portability. Because of this, I decided to construct a similar power supply that runs off of a single 9V battery. Not only is it cheaper to build, it is cheap to operate and it allows me to listen to my radios where I like. Of course, I could have just wired up ten 9 V batteries in series, but that would not be so much fun. https://www.instructables.com/Antique-Radio-B-Battery-Power-Supply/#:~:text=These antique radios required two different batteries for,battery provided the plate voltage to the tubes. https://www.radiolaguy.com/info/About battery radios.htm 1 Quote Link to comment Share on other sites More sharing options...

There are car battery manufactures that make lithium batteries that bass heads use for the primary power source of their systems. https://limitlesslithium.com/products/45ah.html 1 Quote Link to comment Share on other sites More sharing options...

A well dressed young man (suit and tie) was the Representative for a company that made 1 and 2 FARAD (1,000,000 to 2,000,000 Microfarads) capacitors to go in the trunk of the car so that when the Stupid Subwoofers that piss off homeowners and other drivers would not "sag" the instrument panel displays while the 1 and 2 KILOWATT amplifiers were doing their best to vibrate the car apart while killing the hearing of passengers. It's the furthers thing from HI FI. This battery seem to be a product that would appeal to those idiots. 1 1 Quote Link to comment Share on other sites More sharing options...

Proving once again that Ridiculous Overkill is alive and well in the Marketplace. I prefer Big Horns with 10 watt amplifiers for the greatest micro details via low distortion and high dynamic range. For those people it's not about the MUSIC, just bragging rights and show off time. Quote Link to comment Share on other sites More sharing options...
