Rogue Cronus Magnum Dies Help

I was listening to my Rogue Cronus Magnum this afternoon This unit had cap and resistor upgrades done at Rogue by the original owner a couple of years ago., Today suddenly the remote stopped working I changed batteries which were fine I also tried to program a LT 350 but that did not work either I called Rogue but they had no idea. 20 minutes later the volume control started working via remote.

I went for 20 minute walk with the dog. Upon arrival home I found the amp the amp dark No tubes lit , no blue light on. I tried the power button on and off Nothing Unplugged it waited then plugged it in Nothing I checked the power supply fuse and it is fine I checked another large fuse inside. it is fine as are the 4 small ones. Push the power button It does nothing Took it in the kitchen Same thing Dead as a whatever. What happened here?? The main transformer go out??? Thanks
