One possible "repair" is to also just purchase a 12v or 24v heating cartridge (depending on your power supply setup), and drilling then tapping a small hole to secure the cartridge in one of the existing hotend holes intended for the resistors. This obviously does not increase your printable temperature range, due to the limitation of the PEEK, but it gets you back up and running with minimal effort.
As you stated though, many on the forums have upgraded their Rmax V2 hotends to E3D heads. In my case, I went with distechautomation.com and their Prometheus V2, but realistically, any quality all-metal hotend will increase your printable range. Until you get your settings dialed in, you will likely agonize over filament jamming issues in the hotend, but if you persevere, the print quality will return back to whatever tolerances you are capable of calibrating your printer to currently.
If at first you don't succeed, you're doing something wrong. Try again, and if it fails again, try once more. Through trial and error, one can be the first to accomplish something great.
Suspecting one of the Thermal resistors (8R6) failed. measuring them in parallel gave a resistance of 8.6ish ohm...
