	25K/8R	Fender replacement spring line drive transformer	17.00

FENDER SPRING PAN DRIVE TRANSFORMER

Designed for general purpose or replacement use in single ended or phase inverter tube driver circuits.
Open style with minimum 5" long primary leads.
Minimum frequency response 150 Hz. - 15 Khz (+/- 1db max. ref. 1 Khz.) at full rated power.
Part number 124B is the same as our 124A except for 49% Nickel laminations for greater fidelity.
Part number 124C (below) is the COIL ONLY (for those experimenters who want to use their own "iron").

TUBE DRIVER TRANSFORMER

Schematic & Hookup Data: (124E Only)

[Power] [Choke] [Single.ended] [Push.pull] [Line/mic/interstage] [Filament/heater]

Designed for driver use ONLY in single ended tube output amplifiers.
These units replace coupling capacitor circuits for improved sound.
Closed style with minimum 8" long leads.
All models use bifilar wound windings for exceptional coupling and bandwidth.
Minimum frequency response 20 Hz. - 30 Khz (+/- 1db max. ref. 1 Khz.).
The core is gapped to support the specified D.C. bias current.
Core uses Hi grade silicon laminations (29M6).
Units weight - 3 lbs. 2 oz.
