Transformers & Chokes

The LEHLE TRANSFORMER MZ is the ideal component to avoid hum loops without degrading the sound. It achieves this through galvanic isolation of low to mid impedance audio signal sources. It can be used as an input or output transformer, for balanced or unbalanced signals.

• Open style, chassis mount transformers with a 115V 60Hz primary and a 5V center tapped secondary.

• Designed for drop in replacement of original units.
• Physically, parts were designed to look similar to original factory units (where possible).
• Material used & design specs. were kept as close as possible to the original part to preserve the stock "tone".
• See P-T290-FENDER-120 for 120 V transformers, P-T290-Fender-120-UP for upgraded 120 V transformers

Warning: Not all amplifier models of the same name use the same transformer model.

35VA chassis mount Power Transformer for isolating equipment from direct connection to the power line. It is constructed with non-concentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection under normal or overload conditions between the primary and secondary windings. These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system.

The PRC-3 audio choke from One Electron was designed as a plate load for the output of either a high quality line amplifier or a phono preamp.

Open style, chassis mount transformers with a 115V 60Hz primary and an 8V or 8.5V secondary.

Developed in response to requests from the Collins Collectors Association"this is a matching audio transformer for older equipment with 600 ohm audio outputdriving modern speakers. Or for "classic" high impedance speakers used with newer equipmentsimply swap primary for secondary (ie...4 or 8 ohm input and 600 ohms out). Key Features Isolation unit: (i.e.

Features:

• Small, economical, open, two hole horizontal bracket mount.
• Insulated, color coded flexible leads, 4" long minimum
• Frequency response 150 Hz. to 15 Khz. (+/- 1 db, reference 1000 Hz.)
• When operating at impedances below nominal, power capability and the frequency spectrum are proportionately lower, conversely, at higher impedances power capability and frequency spectrum will be proportionately higher.
