Often, but not always, class B stages were driven by step-down "driver" transformers. Some were made as tapped autotransformers which would explain why there is continuity between the apparent windings. Originaly used with pair of KT66 tubes. This code enables easy visual identification. Oct 23, 2003 · Hi All,<P>While thumbing through an old data sheet c. COLOR These standardized systems of color markings are used to indicate the values of small fixed resistors and capacitors, and to provide a means for identifying the various wire leads of audio and power transformers, speaker fields and voice coils, and similar types of components. Audio and Video chat rooms. I assume the numbers seen indicate the number of turns for each winding or winding segment. Except for air-core transformers, the conductors are commonly wound around a single iron-rich core, or around separate but magnetically-coupled cores. When primary coil is connected to 230V, two secondaries output 12V.
