If you do the NPC mod, there realy is no need for volting the finals. The whole notion of volting the finals in these radios, is to make the 2SB754 (Q66) run cooler...if that is a concern for you, it is easier just to replace it with a higher-tollerance 2SB817 (12A-at 100W) it will be cooler and not fail under long QSOs...otherwise, the mod is simmilar. |

even if you do volt the finals, you will only get about 5 more peak watts out of the radio.
if you ssb, then you don't really need to upgrade the voltage reg. all the heat comes from am use where there is a higher voltage drop across the device. |
