Populate shortest parts first.
Step 1: Resistors
R1-R4: 100k Ohm
R5-R14: 499 Ohms
Step 2: Diodes, Beads
D1, D2: 1N4001 (Alternate 1N5819)
FB1, FB2: 68 Ohm @ 100MHz
Pay attention to the diode’s stripe.
Step 3: caps
C3, C4: 100nF (MMLC or film box)
Optional: 8-pin DIL socket
Step 4: Electrolytic caps, power connector
C1, C2: 10uF 25v Electrolytic Capacitors
J9: 2x5 pin male header (or shrouded connector
Pay attention to the polarity. The stripe points to the negative pin.
Step 5: jacks
Place jacks in circuit board. Do not solder.
Step 6: faceplate
Line up faceplate and add nuts to jacks. Finger tighten and once the jacks are straight, solder jacks.
Tighten nuts fully,
Step 7: IC
U1: LM6172
May optionally be soldered directly or inserted in socket.
