Basically a UPS that generates a 120v/60hz sine wave from the battery, and the battery is charged by a switching power supply that works from 100-240v 50/60hz? Rack-mountable, battery capacity: Whatever you can get in 2-3u. Bonus if it's not 24" deep!

If you can let the UPS part go ( how much do you need a UPS for a B3 & Leslie? ) most high end power amps these days are capable of AC input from low 90s to 250 VAC 50 / 60 Hz.  Feed a 60Hz sine wave in ( I think iTechs have built in oscillators maybe Lab Gruppens too ), dial up the gain to get your 120 VAC out and you've got some very clean AC to keep your 1950s technology running.

The "standard" universal power converter is the Kikusui PCR1000M which is USA or European in, clean power at your chosen voltage and frequency out.  No UPS capability though.

Toshiba T1000 series UPSs will do frequency 50 or 60 in, 50 or 60 out, but don't do the voltage conversion.  The smallest model is 1KVA and is available rack-mount.

I used the AR-PRO for years. Worked well for all the crazy power I ran into, no UPS function though. Discontinued many years ago.

Thank you, Pete! I never would have found this without you. I literally have been searching the 'net for days. Hopefully it's reasonably priced!
Here's the current model, for anyone interested...

Yeah, plenty of regulators out there, and that one is being discontinued... Thanks, though!

This is kinda brilliantly "out of the box" thinking.  Now i want to try it.  :)

I think the closest "reasonably-priced" product I can find is a product from CyberPower.
It works from 60-150v, so as long as the local supplier supplies a step-down transformer (those are always easy to get), I think this will work.

Here's a neat video from Powersoft showing off that exact idea.


Given the price of an X8 I kind of expected it would make me fries too!

So it's the AC version of using a 9v battery and a Crown DC300 to power a console. Cool.
