Welcome Taylor K. You certainly came to the right place. Where in Alberta? I have a brother in Calgary. The forum for repair of a TFM-45 would be HERE. You can also navigate there by scrolling down the home page to the Amplifiers section-> Amp Repair-> M-4.0t (also TFM-4, TFM-42, TFM-45). There is a lot of information there as well as there is the Manuals database at the top of the home page. Download the service manual and get familiar with it, including the service bulletins at the end.
