Imagine you buy a cheap&nbsp;professional SS power amp. One of those AB or D class ones which can be bridged to provide 1,5, 2Kw or more. Imagine you feed it with a perfect sinusoidal tone generator set at 60Hz at its signal input,&nbsp;and that you adjust&nbsp;the&nbsp;tone generator's&nbsp;output to read 120V at the speakers output of the power amp. Then all you'd need is feed your gear from the speakers output of that amp. You even could configure this set up to have balanced power if you wish to, and also "fine tune" by slightly varying output voltage and AC frequency within the generator settings.<BR>It's not my idea, a friend of mine thought it. It might work, who knows. My major concern has to do with the impedances the power amp could handle and the input impedance of your gear at its PS.

What you propose has already been made by PS Studio. What I found would be more perspective for someone what would like to do is to make what the PurePower does.

There is a huge army of Class-D amps, for consumer audio and for car audio. You can buy a completed built amp that does 1500W for near $100. It is very small. Add to this amp a 50-60Hz oscillator (it costs nothing) and you have already a good regenerator. Now all that you need to go it to tune your out AC filter for you given load and it is very likely that you get a very seriously performing power source. Sure you do not need any batteries and all that crap….

The PurePower bypass is very good functionality, I tested it and it works wonderful. Still it is possible do not use it if to do even for more powerful class-D amp. There are plenty of class D amps that can pump 25-30A into 1R and it is more then enough, Thos amps are at sub $200 range…  In the worst case it also possible to soften the start of the power amps…

In fact I see quite a good opportunely for someone to see the power regenerator kits where an end user would be able to optimize the parameter of the output AC filter to the amount and the type of the specific load. It might be the direction that I go if the APS folks will not find what it wrong with my PurePower unit. The PurePower Sonic results what low load is used are a very good illustration that the no-transformers, class-D approach might work out very-very well. I am sure that we will see more and more units like this…. With one exception: it is remotely possible that any of class-D amps will suffer from the “do not load me syndrome”… Who knows, will see…
