Hi,

I'm sourcing parts for a 4pi build and was wondering about the value for the Rs resistor rated at 16 ohms for the B&C 250. There weren't any 16 ohm available. I was just wondering if it would be ok to use something a bit higher (18ohm) or lower (12ohm) in this position. Thanks for any assistance.

Either would work, but I'd go with the 18Ω part. The 12Ω resistor will provide more damping, which is good, but it will also attenuate the driver too much, which we don't. Better yet, order the right part online and have it shipped to you.

OK. Thanks for that. I will stick with the parts as suggested.
