Will my 2.4 ohm carts be cool with the 7.4volt upgrade or should I use higher ohm carts?
You'll need five Ohm carts per the chart. Even four Ohm shows Red ("Don't Do It") for 6.3 Volts and above. It shows two stars (ideal). In broad terms 2.4 Ohm carts would be overdriven, four times higher than this (5 Ohm) levels. You'd be hard pressed to keep them from blowing up I'd think.
