  • A new sub-page, Products/Accessories presents our housings for tube OPTs, our new DIN unit for small isolation and splitting transformers and a beautiful case for Moving Coil step-up transformers
  • Audio Engineering Society International Convention 2014, Los Angeles.As usual, Lundahl Transformers will exhibit at the AES International Convention. This year the exhibition is October 10 through October 12 at the Los Angeles Convention Center. We will be in booth 1230, please come see us!!!

New transformer types

September 2014

  • Tube amplifier line output transformer LL2745 is a line output transformer with modest turns ratio (2.8 + 2.8 : 1+1+1+1) and the same internal structure as our well known LL1660
  • Line Input Transformer LL1948 is a new amorphous core line input transformer designed to meet extreme audiophile requirements. The LL1948 is available with Cardas ultra-pure copper wire, or with Elektrisola 99.99% silver wire

  • SILVER WIRE TRANSFORMERS! Our top-of-the-line moving coil stepup transformers are now available with high purity silver wire windings. The transformers are named:

LL1931Ag (1+1 : 8+8, amorphous core) LL1933Ag (1+1 : 8+8, mu metal core) LL1941Ag (1+1 : 16+16, amorphous core) LL1943Ag (1+1 : 16+16, mu metal core)

    • In spite of the small difference in electrical conductivity between copper and silver (approx 6%), the sonic difference is not negligible. Kevin Carter's (of K&K Audio) comments can be found on, A similar report is received from Thomas Mayer via
    • LL1944 is a four output splitting transformer primarily designed for active splitters, speaker boxes etc. The LL1944 is similar to the LL1560, but without the 6dB stepdown from primary to secondary.
    • LL2734 is a low winding resistance anode choke for parafeed and for low current power supply applications.
    • LL1940 is a tube microphone transformer with "character". In the LL1940 we are using a silicon-iron C-core, which is unusual for this type of application. The result is a transformer with more "transformer sound character", compared to a classic mu metal lamination transformer.
