I have an MG machine that accounts for a significant portion of my company's production. If the ACR8000 board was to fail it could cost us in excess of $30k / day having it down. We have had one fail before. For this reason it is imperative I find an ACR8000 backup board. The 8020 is not an upgrade option for us since it is incompatible with MG hardware. If I cannot find a backup board I will be forced to buy a new plasma. Any help would be greatly appreciated.
