Removing the transformer addresses several inherent technical limitations found in traditional designs:
: A classic "totem pole" design where tubes are stacked to pull the signal positive and negative. tube tranny free
: A modern approach by Linear Tube Audio that uses high-frequency carrier waves to mimic a transformer’s impedance matching without the actual iron core. tube tranny free
: Indicates the total absence of these transformers in the signal path. 2. Why Go Transformerless? tube tranny free
Standard tube amplifiers use large iron-core to bridge the gap between high-voltage tubes and low-impedance speakers. A "tranny free" or OTL design removes this component, connecting the vacuum tubes directly to the speaker or headphones.
