You can go further by replacing the two final transistors. Two 2SC2312 by 2 MRF477. Be carefull, these two do not have the same wiring. You will have to cross the pins. (A new modification should be replacing the MRF477by MRF 497 which is more powerful)

Another trick that could be used to boost a bit is to replace R281 (4,7 K) by a 2,2 K value and re-adjust VRs for AM and USB. This boosts the power up to 20 wats AM / 30 Watts USB. Be carefull this is an extreme mod _ May be illegal in your country. Check the law beforehand.
