Strip and tin a 4 ½” length of wire. Wrap one end around the positive lug of the adapter jack (same
terminal as the 220
µ
F capacitor). Now solder this connection and make sure the positive capacitor
lead and wire end are not touching the nearby adapter jack lugs. Connect the other end of this wire
to terminal #6.
Strip and tin a 2 ½” length of wire and connect the adapter jack center-pin lug to terminal #1.

SECTION 5 – Wiring Connections in the Vacuum Tube Section
Terminals #6 & #16
1) Strip and tin a 2 ½” piece of wire and connect:
Terminals #14 & #16
2) Strip and tin a 1½” piece of wire and connect:
Tube Pin 5 to Terminal #14
3) Cut a 1" piece of wire and connect:
Please refer to DRAWING 4.
Tube Pins 3 & 4 to Terminal #13
4) Cut a 3 ¼" piece of wire. Strip 3/8" of insulation
from one end and ¼” of insulation from the other end.
Connect:
Connect the longer end to tube socket pins 3 & 4. Connect the other end to terminal #13.
Tube Pin 2 to Terminal #10
5) Strip ¾” of insulation from the end of the wire supply and tin. Snip off the ¾” piece of tinned wire
and connect:
Stripping and tinning wire:
Throughout these instructions you will be told to strip and tin a length of wire numerous times. Unless noted otherwise,
cut the wire to the length stated in the instructions, then strip ¼” of insulation off each end. Twist each end of the stranded wire and apply a small
amount of solder to each end (tin the wire ends). This prevents the stranded wire from fraying and makes soldering much easier.
Routing this wire along the bottom of the terminal
strip on the side next to the tube socket can make
for a nice insulator to ensure that terminals #15 and
#16 will not short out against the tube socket.
SECTION 4 – Connect the DC Power Components
Please refer to DRAWING 3.
Locate the battery snap connector. Connect
and solder the red lead to the positive-switch
lug of the power adapter jack.

Input Jack
Connect and solder the black lead to ring lug on the input jack.
CENTER-PIN LUG
POSITIVE-SWITCH LUG
POSITIVE LUG
Power Adapter Jack
Connect the positive lead of the remaining 220
