I just finished a 5F2A build and am getting about 370V for my B+1. I want to get that down to about 350 so I put a 300 ohm, 10 watt dropping resistor before the for filter cap. It worked but messing around with the amp for about 5 minutes that resistor was pretty darn hot. I measured the voltage on either side of the resistor to get an idea how much it was dropping and got 355 and 342, so a 13 volt drop. My calculations say that there's 43mA, hence only dissipating 0.559 watts. This seems very wrong. If it's not even 1 watt of dissipation, why is it so hot??
