jack. The solder terminals should be facing the normal channel section.
Step 3
– Install the normal channel LO sensitivity jack (the one deeper inside the chassis) into
the chassis with one fiber washer and with the terminals facing the chassis side.
Step 4
– Install one fiber washer and a grounding washer on the normal
channel HI sensitivity jack and install this jack with these washers into the
chassis above the previous jack. The solder terminals should be facing the
chassis side.
Step 5
– Bend the alignment tab of all of the 1M audio taper pots against the
potentiometer body prior to mounting. Or they can be broken off too.
Step 6
– Install the four 500K audio taper pots in the “volume” and “tone”
control positions of the normal and vibrato channels. Position these controls
with the solder terminals facing up for easy soldering.
Step 7
– Break the alignment tabs off of the remaining 1K w/ switch pot and the 1M pot.
Step 8
– Install the 1K pot with switch in the “intensity” control spot and the 1M pot in the
“speed” control spot. Install these controls with the flat washers on the faceplate side and with
the solder terminals facing up for easy soldering.
Step 9
– Install the two Carling SPST toggle switches in the AC power and STANDBY
positions. Install with the solder terminals facing up for easy soldering.
Installing the 6.3V Indicator Lamp
Step 1
– Twist the wires of the indicator lamp tightly together, being careful
not to pull the body of the lamp out of the back of the red lens.
Step 2
– Feed the twisted wires of the indicator through the front panel
mounting hole.
Step 3
– Once the indicator is in place, slide the press nut over the wires
and firmly slide the nut into place over the body of the indicator lamp and as
flush as possible against the inside chassis front.
Step 4
– Rotate indicator until it is properly aligned and use a little fingernail
polish on this inside push nut to hold it in place.
Wiring the V1 – V5 Tube Filaments
Wiring the power transformer filament center tap
Step 1
– Locate the green wire with the yellow stripe on it coming from the power transformer.
Step 2
– Cut this wire to a 3” length and strip and tin the end.

If you are installing an EF86 instead of a 12AX7 tube as the first channel (normal channel)
preamp tube, then V1 filament will be wired differently than described below. See “Cool
Modifications”, Chapter 11 for more information
Get a footswitchable HI / LO speed control by installing a mini SPDT toggle switch between
the words “vibrato” and “off”. See “Cool Modifications”, Chapter 11 for more information.

This is probably the most challenging task in this entire kit build. Making the filament
installation look great takes great attention to detail and a very lite use of heat when
soldering. I recommend going very slow and be prepared to redo several times. Good
luck.
