This is an eBay (USA) link to the circuit boards and heatsink mounting kit for the hbrown/rcs16 STK0050 upgrade modules. There is a parts list with part numbers for multiple electronic parts suppliers in that listing. Works for SX-790 and SX-780. You will need some assembly and soldering skills to do this correctly. Good Luck!
