I'm planning to modify the 250W PE amp mod, adding 2db to 20-24hz region. 1 question, I bought the 2 resistors from radio shack, 47k ohms and 220k ohms. I didn't know that the 220k ohms from RS is 1/2watt. According to PE instruction, it said 1/4watt. Is it matter if I use 220k ohms 1/2watt resistor? Thanks in advanced. I have everything here and ready to go. Just want to confirm this be4 I take the amp apart. Thanks. Al, Edit: BTW, it's the 250W PE amp part# 300-794.
