I don’t remember hearing you can’t upgrade. You could ask zonna what the board part numbers are between the 4 and the 8. I know you can turn an 8 into a 4. But the power modules would need to be same rev. And if it’s a 4048 not an A, I think it’s about impossible to find anything to work on the non A variants Good luck Jay On Nov 3, 2025, at 7:39 PM, Kirk Herander via RE-wrenches <[email protected]> wrote:
