Anode chokes, interstage, headphone & line output transformers

Lundahl tube amplifier transformers are built in a house-made dual coil single C-core style and can be ordered with a choice of core air-gap for Push-Pull or Single-Ended applications. The use of C-cores with well-defined air-gap results in an almost constant inductance throughout the whole operating voltage range. For SE transformers, the primary inductance variation due to signal level is less than 7%. Most of the chokes and transformers below are available with amorphous iron C-cores. The amorphous cores are considered to have sonic advantages, but the signal level capability with amorphous core is about 30% less than with a conventional silicon-iron C-core.
