Audio Transformer Basics 101

/in /by

We’ve added a new series of reference documents under the “Transformers” menu heading, labeled “Transformer Basics 101”.  These articles were developed and authored for Lundahl Transformers by a well-known pro audio designer, Ken DeLoria.  These provide an excellent introduction to audio transformers:  rationale for use, applications examples, construction/manufacturing, and a bit of transformer theory and math.  Please feel free to browse these six “white papers” and take away information that can help you design better audio equipment.

Amplifier Input Stage and Power Supply Kits

/in /by

These kits are now all in stock ready to go.  They make amplifier construction using the output stage of your choice straightforward and sonically rewarding.  A few early adopters have already built PP amps using the interstage transformer input stage and a variety of output tubes, including PP 6C33C and PP KT150 tubes.  Pictures and descriptions are forthcoming.

To sweeten the deal, we are offering a 10% discount on any amplifier components order that includes, but is not limited to, the following:

  • 2 channels of input stage kit (including the interstage transformers, if applicable)
  • 1 or 2 power supply kits
  • 2 channels of Lundahl output transformers

Give these a try for your next amplifier project!
