31. ( ) Insert the .01uF disk capacitor C6 into the
perfboard and bend the leads out slightly to keep the
capacitor in place. Disk capacitors do not have a polarity
so it does not matter which direction the capacitor is
inserted into the perfboard.
32. ( ) Strip ¼" of insulation from each end of a 1" piece
of wire. Connect one end to potentiometer R7 lug C and
solder all wires to lug C. Solder the other end to resistor
R5 and capacitor C6 as shown in Fig 1.
33. ( ) Solder resistor R5 to capacitor C8 as shown in
Fig 1.
34. ( ) First solder capacitor C6 to the bare wire from
variable capacitor C5 and coil terminal T3, and then
solder C6 to resistor R5 as shown in Fig 1.
35. ( ) The AF detector and amplifier circuit is now
complete. Check that all components and wires in the
AF/Detector stage have been properly soldered. Trim
leftover leads flush with their solder joints.
36. ( ) Insert .01uF disk capacitor C1 into the perfboard.
Solder one end to the bare wire from the Antenna Ground
pin of terminal strip T2 as shown in Fig 1.
37. ( ) Insert 33K resistor R1 into the perfboard. Solder
one end to the bare wire from the Antenna Ground pin of
terminal strip T2 as shown in Fig 1
38. ( ) Insert 1K resistor R3 into the perfboard. Solder
one end to the bare wire from the Antenna Ground pin of
terminal strip T2 as shown in Fig 1
39. ( ) Insert 47pF capacitor C2 into the perfboard.
Solder one end to the bare wire from the Antenna Ground
pin of terminal strip T2 as shown in Fig 1
40. ( ) Strip ¼" of insulation from each end of a 1" piece
of wire. Solder one end to potentiometer R2 lug A and B.
Solder the other end to capacitor C2 as shown in Fig 1.
41. ( ) Solder capacitor C1 to resistor R1 as shown in
Fig 1.
42. ( ) Solder capacitor C2 to resistor R3 as shown in
Fig 1.
43. ( ) Insert 15pF disk capacitor C4 into the perfboard.
Solder one end to the Antenna pin of terminal strip T2.
44. ( ) Insert 100K resistor R4 into the perfboard. Solder
capacitor C4 to one end of resistor R4 as shown in Fig 1.
45. ( ) Bend the leads of NPN transistor Q1 as shown in
step 24 and insert into the perfboard. Make sure the flat
side of the transistor faces toward the back of the radio as
shown in Fig 1. Solder the emitter lead to resistor R3 as
shown in Fig 1. Solder the base lead to resistor R4 and
R1 as shown in Fig 1. Solder the collector lead to
resistors R4 as shown in Fig 1.
46. ( ) Insert 47pF disk capacitor C3 into the perfboard.
Solder one end to the emitter of transistor Q1. Solder the
other end to the collector lead of transistor Q1.
47. ( ) Strip all insulation from a 1" piece of wire. Solder
one end to capacitor C3 as shown in Fig 1. Solder the
other end to the bare wire from coil terminal strip T4.
48. ( ) The RF regenerative stage is now completed.
Check that all components and wires in the RF stage
have been properly soldered. Trim leftover leads flush
with their solder joints.
49. ( ) Install the small knobs on potentiometers R2 and
R7 and tighten the set screws until the knobs hold firmly
to the potentiometer shaft. Install the large knob on the
tuning capacitor C5 and tighten the set screw until the
knob holds firmly to the tuning capacitor shaft. Do not
overtighten the set screws.
50. ( ) Remove ¼" of insulation from both ends of a 16-
1/2" piece of wire. Holding the wire as shown in the
drawing below, wrap it around a "AA" battery for 8 full
turns. Leave at least ¼" left over for lead length.
