Fender 57 Custom Deluxe Mode D'emploi page 3

J. POWER CORD: Connect to a grounded outlet in accordance
with the voltage and frequency specifications noted on the
amplifier information label, which is located inside the cabinet
on the left when viewing from the rear.
K. RECTIFIER TUBE: Single 5Y3 rectifier tube converts AC voltage
from the amplifier's power transformer into DC voltage required
by the power (L) and preamp tubes (O). It should be replaced
only with an identical rectifier tube.
L. POWER TUBES: Dual 6V6GC power tubes drive the power sec-
tion of the amplifier. These should be replaced only with identi-
cal power tubes or those with a comparable rating and quality.
M. INTERNAL SPEAKER JACK: The '57 Custom Deluxe's single inter-
nal speaker connects here. A single external speaker can also be
used instead of the internal speaker, but it must be rated at 8 ohms
and a minimum of 12 watts, and it must be connected to this jack
and not to the Extension Speaker Jack (N) (note that this requires
disconnection of the internal speaker).
Note that the amp can be damaged by using a single external
speaker with a rating other than 8 ohms, or by using a single ex-
ternal speaker of any rating plugged into the Extension Speaker
Jack (N) with nothing plugged into the Internal Speaker Jack.

Whether internal or external, an 8-ohm speaker must be con-
nected to the Internal Speaker Jack when the power is on, or the
amplifier can be damaged. Also note that using the '57 Custom
Deluxe's internal speaker and an external speaker simultaneously
is not recommended.
N. EXTENSION SPEAKER JACK: The extension speaker jack is for
use only when using two external speakers (note that this requires
disconnection of the internal speaker). When using two external
speakers, they must be rated at 16 ohms and a minimum of 12
watts each, to achieve the acceptable combined rating of 8 ohms
(use of two external speakers with ratings other than 16 ohms
each can damage the amplifier). Also, as noted above for the
Internal Speaker Jack (M), using the '57 Custom Deluxe's internal
speaker and an external speaker simultaneously is not recom-
mended.
O. PREAMP TUBES: Dual preamp tubes drive the preamp section
of the amplifier. These consist of one high-gain 12AX7 preamp
tube, and one 12AY7 preamp tube for original-era lower-gain
tone. These should only be replaced with identical preamp tubes
or those of comparable rating and quality. A second 12AX7 tube
can be substituted for the 12AY7 tube to achieve a more modern
higher-gain tone.
