ELECTRICAL SPECIFICATIONS

Characteristics

Typical

Input Impedance

5000/8000 Ohms

• Designed for drop in replacement of original

units.

• Constructed to look similar to original factory

units (where possible).

• Material used & design specifications were kept

as close as possible to the original part to

preserve the stock "tone".

• Open style with minimum 9" long primary and

secondary leads

• Frequency response 70Hz - 15KHz

(0/-1dB reference @ 1KHz)

• Distortion is less than 1% @ 70Hz
