Chassis Rear View
L. POWER CORD: Connect to a grounded outlet in accordance
with the voltage and frequency specications noted on the
amplier information label, which is located inside the cabinet
on the left when viewing from the rear.
M. RECTIFIER TUBES: Dual 5U4 rectier tubes convert AC voltage
from the amplier’s power transformer into DC voltage re-
quired by the power (N) and preamp tubes (P). These should be
replaced only with identical rectier tubes or those of compa-
rable rating and quality. If preferred, one rectier tube may be
removed for a dirtier blues tone.
N. POWER TUBES: Dual 6L6 power tubes drive the power section
of the amplier, and are matched and rated for high output.
These should only be replaced with identical power tubes or
those of comparable rating and quality.
O. SPEAKER OUTPUT JACK: The ’57 Custom Twin-Amp’s two inter-
nal speakers connect in parallel to this single jack. Alternately, the
internal speakers can be disconnected to allow use of an external
4-ohm speaker cabinet (40 watts minimum). To prevent damage
to the amplier, one of these two congurations must be con-
nected when power is on.
P. PREAMP TUBES: Four preamp tubes drive the preamp section
of the amplier. These consist of two high-gain 12AX7 preamp
tubes, and two 12AY7 preamp tubes for original-era lower-gain
tone for both the Bright and Normal channels. Alternately, two
more 12AX7 preamp tubes can be substituted for the two 12AY7
tubes to achieve higher gain. Note: For extra shielding against
electrical hum, two custom-made 1950s-spec steel tube shields are
installed on the rst two preamp tubes (V1 and V2).
Rear panel, tube cage, preamp tube shields and other parts removed for illustration.
