As of my last update in September 2021, Class T power amplifiers are not a well-known term. It's possible that developments have occurred since then, but as of that time, Class T is not a recognized class of power amplifier. Therefore, I cannot provide specific advantages and disadvantages for a Class T power amplifier.
However, I can provide information on some common classes of power amplifiers that are widely used, such as Class A, Class AB, Class B, and Class D. If you were referring to one of these classes or another class, please let me know, and I'll be happy to provide the information you need.
