This project is mostly done. Still doing a few refinements, but it is nice and up-to-date having high definition wide screen TVs in all the original places. Tom, I did use those Pyle amps on each TV and they do a great job of getting sound out of the 5-1/4" speakers.

When inverting power, there is a "buzz" in the background that I presume is from the modified sine wave inverters. I haven't found a filter.

The living room and bedroom audio items are on the same circuit. Perhaps I could do a small pure sine wave inverter just for that circuit? Haven't thought how that would wire up.

Or I guess I could replace the inverter on that leg with a new pure sine wave inverter. That sounds like a big event.

Any other thoughts? I guess I could just have good audio when plugged in or the generator is on and give up on the dry camping for good audio. Really rather have it good all the time.
