Why can't you have battery powered electrostatic amps?

There are already 3 portable electrostatic amps. Two from stax and one from
koss.

Soon there will be four

Oh no. He's at it again......and I can't wait!

A battery is just an alternative power source from using the mains. Anything can be battery-powered, as long as the battery is big enough.

more like a voltage multiplier,an couple of example of which can be seen over at Steve Bench's web page.

Take any 12 volt battery,connect it to a "backwards" 12VAC transformer and you will get 120 volts out (instead of the normal use where 120 VAC in=12 VAC out).Use diode voltage multiplier network on this and you are in the 300VDC range and the only question becomes how much current you need to go with that voltage "upper"

You never cease to impress Mr Gilmore.


Something with a similar form factor to the SRM-001 would be sweet, hint hint.

It might be obvious to us, but I know a lot of people who don't think things through logically.

2 from Stax!? Have i missed something here? Tell me quick, maybe i must cancel the order i have on audiocubes..

Err, no. Transformers work with alternating current, not DC. So you'd need to convert the battery's DC voltage to an AC signal first, probably by adding an oscillator driven transistor switch to create a square wave. Voila, a "switching" DC-DC power supply.

even better :

Lower voltages but ingenious just the same

the "real deal" ready for prime time audio :

but I DO have a transformer/diode voltage multiplier right here within three feet of my person that uses a nine volt battery to get 120 volts using a simple transformer/diode circuit.Call it a "zapper" for the unsuspecting.not enough current to do any harm but enough voltage to give someone a wakeup call

I guess you could say two since there was an SR-001 before the SR-001MK2
(Mark 2).
