Expert? Hardly. Crispy rust bucket's more like it. I was lucky to find the shoulders-of-giants to peek over to get me stumbling back into the game is all. But adding a jack that'll disconnect the internal speaker when an external cab is plugged in, is relatively easy.
Use a switched-mono 1/4" phone jack. First, connect the OT's output ground wire to the jack ground lug, and extend that (add wire) to connect it to the speaker's ground lug.
Run the OT's output hot wire (the red one) to the tip lug of the jack. Run a new wire from the switch lug (the tip's switched lug if using a Cliff Jack, or just THE switch lug if using a Switchcraft jack) to the speaker's hot connector. This will connect the internal speaker to the amp through the jack when nothing is plugged in, so be sure to keep that jack clean and well maintained for best tone. DeOxit D or G-series spray (formerly ProGold) is excellent for this job)
Simply swapping out the speaker should be a straightforward affair if quick connects are used on the OT wires. If so, try to spread the quick connect crip apart so it'll slide off the speaker lugs easily. Crimp them gently with pliers before reinstalling and make sure there's a snug fit. Personally, in terms of 12" drivers anyway, I prefer a single 20w greenback with my 18watt Marshall clone, but I moved that to a closed back cab cuz it sounded so much better in there. I've also run a 15watt Alnico Blue. Currently I run a G12H-30w bass cone in that combo now. It's louder. None has shown any sign of danger toward burning up the voice coil, and they've all survived it just fine. That Vintage 30 is rated for 60 watt, and will have no trouble with anything an 18watter can throw at it.
