Hammond 194A 4H 50mA Power Supply Choke for Deluxe Reverb Amps

The 194A is a 4 H power supply choke for Fender tube guitar amplifiers, rated for 50 ma. of D.C. current. It is listed for the Fender Deluxe, Deluxe Reverb, Vibrolux, Vibrolux Reverb 1964 and Blackface 6G15 Reverb, and it is equivalent to Fender part numbers 125C3A and 022707. Amp technicians and restorers use it to replace a failed or noisy filter choke in the B+ supply of these amplifiers.

Inductance is 4 H with a +/-15% tolerance. The 50 ma. rating suits the lower-current supplies found in these amplifier models. The manufacturer short description reads "CHOKE 50MA, 1500 OHMS".

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.

The 194A carries UPC 623980094199 and UNSPSC 39121301, and its listed shipping weight is 0.1 lbs (0.05 kg). It is RoHS and REACH compliant. Fender model names are trademarks of their owner and are listed for reference only; Hammond is not affiliated with Fender Musical Instruments Corp.
