  That is correct...it must be plugged in all the time. The 193L in parallel only draws 64mA on a 120v 60Hz line...that's nothing...the choke is designed for 300mA. The choke will remain ice cold. Just to be clear...I do not recommed this choke for 220v or 240v 50Hz applications. It should still be safe with those voltages, but I haven't had good results. On the other hand I have had excellent results with 120v 50/60Hz applications.

  You should use a 14ga x 3 power cord. Use the earth ground wire to ground the choke at the chassis mount. It makes a audible difference. Also...keep the power cord as short as possible for best effect....under 3 feet.

    After extensive testing I have changed my no go for 220 / 240v to a go. The Hammond choke is fine to use on a 220/240v 50Hz line. The benefits are impressive.

  • is there better way to connect wires other wire nut? - michaelv20850 13:58:57 04/20/07 (2)

    In the meantime, i just use wire nut to connect wires together and then use electric tape to mask them for safety issue.

    Any idea to make it looks nicer? I guess put everything in a plastic case can help...:) uhm...i try to figure out something.

    thanks.

      Most wire nuts contain steel springs and are bad for sound. The connection will be dirty and noisy once the copper corrodes. You would get better results, IMO, by splicing and soldering the connections. Use polyolefin heat-shrink and beef up the insulation with rubber electrical tape.

      If you connect the choke body to AC safety-earth, try it with a direct connection and with an anti-parallel pair of 6-amp rectifier diodes in the safety-earth lead.

      My demo units use a Hammond extruded aluminum hobby box, but I am looking into exotic wood cases for commercial use.
