The photographs shown are indicative and may not exactly match the product supplied. The bandwidth measurements were taken in the actual circuit using the specific tube for which the transformer was designed. These measurements are performed at about 1 Watt RMS using the typical tube bias current. Note that once integrated into the respective circuits, the introduction of negative feedback—especially recommended with pentodes—can significantly extend the bandwidth and limit phase shifts across a wide audible range.
