Se hela listan på diyaudioprojects.com The LL1664 is a four-sectioned dual coil C-core tube amplifier output transformer for 3 k: 8 ohms impedance ratio available in PP and SE versions. The coil is wound using our high internal isolation technique with isolation foil between each copper layer. LL1688 is an output transformer, designed primarily for 845 tube amplifiers, but the LL1688 is available with different core air-gaps for different types of output stages. The transformers are highly sectioned with harmonically sized sections, Lundahl Output Transformers. Single Ended and Push Pull.
Lundahl silicon iron C cores Driving circuitry for line output transformers should have low output impedance. In order to reach the very best performance in terms of low distortion and low line output impedance, we recommend that our output transformers are used with mixed feedback drive circuitry for negative output impedance and best THD performance. 10 rows LL1679 is an output transformer for tube amplifiers, available with different core air-gaps for different types of output stages. The transformers are highly sectioned with harmonically sized sections, which results in a minimum leakage inductance. This combined with a low capacitance coil winding technique results in a wide frequency range.
