Carbon Resistors
 
I have just come upon a whole slew of Motorola Carbon Composite resistors from 10-10-2 through 4.7M-10-1/8 in pretty good quantity.
I was wondering about the possibility of using a bunch of 22-10-2's in parallel to get the value needed for the series resistor in my L-Pad circuit.
Would there be any benefits/downsides in relation to using Non-Ind Dayton resistors?

Carbon resistors tend to be less bright. It can be positive can be negative depends on taste. That is if you can hear the difference.

Not so much. All the extra lead length might add a little bit of inductance, but we're talking pretty negligible. I had built a couple of sets of speakers using massively paralleled carbon resistors for just that reason (I had a few hundred 15 and 20 ohm 2W carbons) and they performed just as you'd expect whether the resistors were carbon, wirewound noninductive, or metal film. It did make the crossovers look a bit bizarre.

Thanks, I just have about 200 assorted 2W CC resistors and I just CAN'T let them sit there.
It's worse than a kid with money in a candy shop.
