• 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-UP for upgraded 120 V transformers, P-T290-FENDER-240 for 240 V transformers

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

The Lehle Transformer HZ is the ideal component to avoid hum loops or to balance and unbalance signals without degrading the sound of high impedance signal sources.

Developed in response to requests from RCA Radiola III-A collectors. The original transformers are usually found with open" windings due to the fine wire and high turns usedcoupled with age. This is a universal replacement type - it will replace any of the three audio transformers used (1st audio driver2nd audio-phase splitter stage or output transformer)by correctly connectiong the 5 lugs. A pin out and connection diagram is included. The cases from the old transformer will fit this new unit. The terminal board is a duplicate of the original.
Key Features

• Secondary: 12000 turns C.T., #41 wire (lugs 5 & 1lug 3 is C.T. connection)
• Termination: Solder lugs on a 1 3/4" x 1" terminal board with 4-5" connecting leads
