Thanks for the vote of confidence, but I have made my share (or more) of mistakes posting here. I like to think I'm batting above .500 and improving, though!
Revsdr, before you go changing the transistor, power up the console and try this: press a finger on the clear & silver capacitors near the adjustable choke, and jiggle or rock your finger back and forth a bit. If the static changes in response to your pressing or moving your finger on them (possibly including the game sound coming in), they're bad, and the transistor is probably good.
Some consoles do have other transistors, usually near the 3.58 MHz frequency crystal. The one you want is also near the adjustable choke, usually with 3563 marked on it.
How did you make out with the Audio. I have the Field Service Guide if you need some help? Worst Case Give Best Electronics a call. Brad knows his stuff. I think anyone who has talked to him knows what I'm talking about.
