This kit uses power passing chokes to help engineers minimize the effects of hum modulation in cable TV applications. The kit contains parts to design a choke to withstand 15 continuous amperes and a peak current of up to 25A for two hours. Several windings are provided for balanced 10:10 turn types or the 10:2 turn versions. A dampening resistor connected between the center tap, the winding, or either outer leg can be used, and a variation can be made by placing a dampening resistor across the other sections of the windings. One version has a 470 ohm dampening resistor across 12 turns on the 10:12 coil. The type of circuit will ultimately determine which type of choke will be more effective. Although a 470 ohm resistor is on the lower potential winding, users can experiment with various resistor values and placements on the winding to obtain the desired results. Call for pricing.
