Hi @Mojo292 and welcome to the forum!
You did the correct steps, but something is wrong if you see smoke. A component is getting too hot. Can you confirm you see the fan is running? If you run the unit with flat toggle switch settings, does that make any difference? What is the output level with Jose? Do you see the same thing happen with the Astro 20? Does the room have good ventilation?
Next steps might be a much closer visual inspection of the board, but only if you want. For example, check the photos in this thread: Blown capacitor C503 on the inductor board
We can take it from there and service it if we see problems.
