UPS to DC power supply

[darknuss]

I have an APC model SUA1500 UPS, (uninterruptable power supply). How difficult would it be to convert it to use as a power supply for a DC linear amplifier? The specs are here: www.apc.com/resource/include/techspec_index.cfm?base_sku=SUA1500&tab=models
Output at AC outlets is 1440VA, whatever that means lol lol lol. I'm hoping it can be done to save some stamps I can put to use on a big FET box.

The battery used in that UPS is a 12 volt 18 AH battery. That would maybe power a two transistor 12 volt amplifier for maybe 10 minutes.

I figure if say 12>24volts DC is used to keep the battery charged how many amperes is it capable of delivering.

The APC chargers aren't designed to deliver that kind of current, just to recharge the battery pack.

You'd be better off with a power supply, in my opinion.

I've been doing some research and a better move for me is getting a steel tube linear that's plug and play. Thanks for all the feedback.

Tube amplifiers are good, but remember they do have to be tuned for use. So they really aren't "plug & play" although tuning isn't that hard once you get it. And they do have to be re-tuned as you move around the band, especially if you go into the freeband area.
