Well less current yes, if we are talking doubling the resistance. I was more referring to putting 2 500 ohm resistors in parallel, giving the same equivalent resistance, but helping to better dissipate the heat, by halving the current through each resistor.
I agree, I'm scared if that is 500ohms. Hell I'm scared if its 1k: I used 1K on my VanTOTL and I used 2 25 watt resistors in parallel to deal with the heat.
