38. Trim to length and connect the four Left output transformer leads (Yellow,

Orange, Brown, Black) to the Left speaker output terminals as shown in figure 1.

39. Prepare a 15" black / green twisted pair of 22 ga.Teflon insulated wire. From one

end connect the black lead to the speaker output terminal that is connected to the

left output transformer Black lead. At the same end connect the green lead to the

speaker terminal connected to the left output transformer Yellow lead. Route the

twisted pair along the left edge of the amplifier and then along the front of the

amplifier so that it arrives near the input terminals.

40. Trim to length and connect the four Right output transformer leads (Yellow,

Orange, Brown, Black) to the speaker output terminals as shown in figure 1.

41. Prepare a 15" black / red twisted pair of 22 ga.Teflon insulated wire. From one

end connect the black lead to the speaker output terminal that is connected to the

Right output transformer Black lead. At the same end connect the red lead to the

speaker terminal connected to the right output transformer Yellow lead. Route the

twisted pair along the right edge of the amplifier and then along the front of the

amplifier so that it arrives near the input terminals.

42. Connect the shorter of the two power transformer black leads to the center lug of

the fuse holder as shown in Figure 1.

43. Connect the remaining (longer) black lead of the power transformer black leads to

terminal 1 of the power switch as shown in Figure 1.

44. Locate the two the Power transformer (not output transformer) Red leads and

lightly twist them together orienting them toward the left past the underside of V1

(rectifier tube socket). Trim to length and connect one to V1/pin 4. Connect the

remaining red wire to V1/pin6.

45. Locate the two the power transformer White (due to age these may also appear as

Yellow) leads and lightly twist them together orienting them towards the V1

(rectifier tube socket). Trim to length and connect one to V1/pin 2. Connect the

remaining red wire to V1/pin8.

46. Locate the power transformer Green/Yellow lead and the power transformer

Brown/Yellow lead. Twist (if possible). Trim to length and attach one lead to the

first lug (nearest the front of the amplifier) of the 4 pin terminal strip (this lug also

connects to one of the outer leads of the ceramic cap). Trim to length and connect

the remaining lead to the third lug of the 4 pin terminal strip (this lug also

connects to the remaining outer leg of the ceramic capacitor).

47. Locate the power transformer Red/Black lead and connect this to lug #4 (the

remaining free lug, nearest the power transformer) of the 4 pin terminal strip

mounted between the bias potentiometers.

48. Locate the power transformer Red/Yellow lead and securely connect it to the

ground lug (center lug) of the 3 lug terminal strip located to the right of the right

bias potentiometer (near the original Quad electrolytic capacitor). Make Note -

This is system ground.

49. Locate the Red leads for each of the output transformers and route each to appear

near the 3 lug terminal strip. Trim to length and attach to lug #3 (nearest the
