SECTION 5 – Connect Rear Mounted Components
Drawing 7
shows the inside of the chassis as viewed from the front looking at the rear.
1) Intertwine the green and black wires from TR2 and connect their ends to the output
jack with black to the tip lug and green to the sleeve lug.
2) Connect the black wire from TR1 to the fuse holder’s outer solder lug. Prop this lug slightly away from the
fuse holder’s plastic body and plan for a little slack before cutting.
Connect to the output jack and fuse holder:
Connect T6 and V2 components:
1) Connect the 470Ω resistor from T6(5) to V2 pin 9.
2) Connect the 5.6kΩ resistor from T6(3) to V2 pin 2.
3) Connect the .022µF cap with from T6(3) to T5(3).
4) Connect the remaining 220kΩ resistor from T6(3) to T6(1).
5) Connect the 150Ω, 5 watt resistor from T6(1) to V2 pin 3, but
do not solder at pin 3, yet
.
6) Connect the 100µF cap with negative end to T6(1) and positive end to V2 pin 3. Solder all connections.
Connect the transformer wires:
1) Intertwine TR1's two green wires and connect one to each of the two solder lugs on the lamp holder. (It
doesn’t matter which green wire connects to which lug, just don’t connect them to the same lug). Leave room
at each terminal on the lamp holder for a future wire connection from the lamp holder to the tube filaments.
2) Connect TR1's white wire to power switch lug 3.
Tip: Before connecting transformer wires, measure the best wire length by running the wire along its actual
path (as shown in the drawings) and then cut it with your wire cutters at a length that will give it a little bit of
slack after stripping off the insulation and soldering. (It’s important not to make the wires too long).
3) Connect TR1's red/yellow wire to T2(1).
4) Connect one of TR1's red wires to T2(4) and its other red wire to T2(6).
5) Connect TR2's red wire to T2(3).
6) Connect TR2's blue wire to V2 pin 7.
