I brought this around 25 years ago (sn#12)when I had a second home in the country as the power was horrible and all over the place (105 to 127) and noisy
It died around a year ago and sadly ps does not fix it and offers a discount on other stuff
Around 10 years ago after hurricane ida the damage up here was really bad and I fought the power company and got my own pole and transformer ,it's been fantastic
So instead of salvaging for parts or dumpster contenders,I thought a simple 60 hz signal generation to an amp to get 120 v out
Am I dreaming or is it possible as it's just a ac generator
Thanks

If the amp is rated to deliver that power level continuously, yes on a sine wave current basis.
But since the usual power supply in linear audio amplifiers draws high current pulses,
it may have trouble delivering those current peaks, or even current limit.
Can you give more details on what you need? Why can't the power company deliver 120VAC to you?
What voltage is available from the pole/transformer, is it only 240VAC?
It's possible the PS Audio (which is an AC voltage regulator) has provisions for 240VAC input
in its power transformer, which could be easily converted from 120 to 240.

1000W/8ohms is not quite enough for 120v. Perhaps with a 2kW amp or a bridged 1kW or with a step up transformer. Don't think i have ever heard of such a diy project. Fixing the PS Audio may be simpler.
What you need is an online UPS. They are class D "amplifiers" designed specifically for the task. Also as all UPS's has batteries that are contantly charged and being monitored. Those UPS's give cuasi perfect sine output. I had repaired several of them at job.
See for example this one. Note I have no any commercial job with this manufacturer but they are common here

Ha I guess I should be more clear,my power supply is fine,I just want to build a ac regenerator in the existing chassis,it has a huge ps ,while I am not sure about the output I could make a decent D.C. Supply,but most class d have their own ps anyway.
If that is not possible I could build a class a amp but don't need one
Osvaldo yes this is what I would like to do but dream I y.
Analog no one wants to fix this and it's heavy around 80 lbs
Thanks

Sincerelly. I can't undestand. You want to make your class D amp to behave as an DC to AC converter?
You can do that, but why?

I have been doing diy audio for 50 years and still want to learn and share,perhaps someone might want to build one where they don't have good power supply and can't afford $$$ equipment,plus I have always recycled and up cycle stuff,I also feel guilty of throwing a $ 4K piece of equipment in the dumpster
I will think about this during the holidays with help of food and booze
