POWER MODS

INCREASE YOUR POWER ! ! ! ! !

You can boost your output power in both AM/FM and USB which are driven separately. Have a look at this drawing.
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.
