Is 300 volt wire enough?
If the voltage potential between the wire and everything it could possibly touch (or come extremely near to) is less than 300 volts, yes. But if it gets even close to that, you should consider using wire with insulation having a higher breakdown voltage. Otherwise a power line surge might cause problems. • All I care about in resistors is resistance, right? • What wattage resistor do I need? With resistors, you generally care about the following criteria: • Resistance : this is the obvious one. • Tolerance : for guitar amps, 5% to 10% is fine, depending on taste and availability. If you’re really picky, go with 2% or 1%, but expect to pay more. • Wattage : make sure you use a wattage rating higher than the resistor will ever see. I like to have 25% or more power in reserve. For instance, if I calculated a resistor would dissipate 0.9 watts, I would use at least a 2W resistor, not a 1W. • Type : some people insist you need carbon comps for a true, vintage sound, but carbon comps drift m
