Hammond Transformers Model 193Q

Hammond Transformers Model 193Q (193 Series)D.C. Filter Choke – 10 H, 500 ma, 53 Ohms, 1000 Volts D.C.This enclosed common mode D.C. filter choke is perfect for high voltage power supply filtering. Its case matches power transformers & tube audio output transformers. The units are vacuum impregnated with polyurethane varnish for quiet and long-life operation.Proper Henry testing requires an LCR meter in junction with a 25A power supply that does allow for DC bias as well a higher applied AC drive voltage to meet the test specifications.Features:Enclosed, 4-hole mount chokesTolerance of 15% on both inductance & resistance.Inductances measured at rated D.C. current.Minimum 8″ long leads.Units will exhibit less inductance at slightly higher currents or more at lower currents.Perfect for high voltage power supply filtering, case matches power transformers & tube audio output transformers.Units are vacuum impregnated with polyurethane varnish for quiet and
