Hammond 194C 40H 50mA Preamp Choke for Plexi and JCM800 Amps

The 194C is a 40 H power supply choke for Marshall tube guitar amplifiers, rated for 50 ma. of D.C. current. The series table lists it for the pre-amp supply of Plexi and JCM800 models, and the manufacturer short description identifies it as a choke for the Marshall JCM 800. It suits technicians servicing or restoring these amplifiers who need a drop in replacement.

Inductance is 40 H with a +/-15% tolerance, the highest value among the Marshall entries in the 194 Series, where the 194F (5 H at 120 ma.) and 194G (3 H at 250 ma.) cover the main supply positions of other models.

Like every 194 Series choke, it was designed for drop in replacement of the original unit and physically designed to look similar to the original factory part where possible. Material and design specifications were kept as close as possible to the original to preserve the stock tone, and the unit is vacuum impregnated with polyurethane varnish for quiet and long life operation. Inductance is measured at the rated D.C. current, so the published value reflects real operating conditions.

Shipping weight is 2.36 lbs (1.07 kg). The 194C carries UPC 623980094304 and UNSPSC 39121301 and is RoHS and REACH compliant. No equivalent Marshall part number is listed.
