Construction Supplies London Power Custom Transformers Hobbyists and amp builders can now use the same high quality transformers and chokes found in London Power's own amp line. All of our power transformers incorporate dual primaries for world-wide mains compatability, an electrostatic screen to isolate line noise, and a flux band to contain magnetic leakage - even on the toroids. Our output transformers feature direct-impedance matching, ultralinear taps, flux band, and wide power bandwidth. Our chokes are all fully shielded and have flux bands.
