Preliminary Wiring of Tube Sockets
Step 1 – Wire a 100K / 1/2W resistor to the back of the
V2 socket as shown (drawing 5.6a). Do not apply
solder to pin 6 just yet.
Step 2 – Wire a jumper wire across the back of the V3
(pins 3 & 8) socket as shown (drawing 5.6b). Do not
apply solder to pin 8 just yet.
Step 3 – Wire a 5.6K / 1/2W resistor to the back of V4
and V5 sockets as shown. Do not
solder where indicated (drawing 5.6c).
Step 4 – Wire a 1.0 / 1W resistor to
pins 1 & 8 of V4 and V5 sockets as
shown (drawing 5.6C)
Step 5 – Cut four 3/4” pieces of
recycled 20AWG plastic wire
insulation and place over the leads of
the R3000 diodes.
Step 6 – Wire the two R3000 diodes
to the V4 and V5 sockets as shown
(drawing 5.6C). Pay careful attention
to polarity of diodes.
Installation of Hardware, Transformers and Faceplate
Step 1 – Install the power transformer with the yellow
wires coming through the chassis cutout toward the rear
of the chassis. Refer to drawing to determine the proper
location of the four #8 solder terminals (drawing 5.7a).
Use three standard #8 nuts on the solder terminals and
one KEPS #8 nut on the remaining mounting bolt.
Step 2 – Install the four aluminum standoffs to the
chassis with four #6-32 x 1/4” screws.
Step 3 – Install the output transformer with the red, blue
and white wires coming through the grommet nearest
the front of the chassis and with the remaining yellow,
orange, violet, and black wires coming through the
grommet nearest the back of the chassis. Secure with
four #8x32-3/8” screws and four #8 KEPS nuts.
Step 4 – Install the choke with the two black wires
coming through the remaining grommet. Secure with
two #8x32-3/8” screws and two #8 KEPS nuts.
Step 5 – Remove protective plastic from faceplate and rear plate.
Step 6 – Install faceplate along with input jacks, master volume, volume &
tone controls, power and standby switches and indicator lamp (with rear lock washer). Refer
to drawing for proper component alignments (drawing 5.15c).
Step 7 – Install IEC AC power entry connector into the square cut out on the back of chassis
