During the last year Lundahl Transformers have developed a new line of Single-End to Single-End 1:1 interstage transformers. When conventional design practice is applied to this type of transformers you easily get destructive capacitive coupling between the primary and secondary windings. This will reduce the HF bandwidth and increase HF ringing. After a more thorough [...]
A nice (we think!) preliminary review of the Cable Factory DI-Pro with our LL1530 transformer. DI boxes are used e.g. when you connect your electric guitar to a microphone preamp input. Thank you! We look forward to the final review when the unit is fully tested. Click here to read the review
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. Products/Accessories.
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 [...]
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 [...]
