Diode Waveform Shaper Construction Notes (11/9/02, updated 02/22/03)

Install the following components using organic solder. Remember to wash the boards off.

Insert the following resistors:

271-100K (32) (Note on R70: This gives the breakpoint a 10 volt range. To give it a 5 volt range that is more compatible with MOTM systems, make this a 49.9K resistor.)
R1,R10,R12,R15,R16,R17,R18,R19,R20,R21,R22,R23,R24,R25,R26,R39,R40,R41,R42,R43,R44,R45,R46,R47,R48,R49,R50,R70,R74,R75,R78,R79

271-30K (1) (Note: This gives the breakpoint a 10 volt range. To give it a 5 volt range that is more compatible with MOTM systems, make this a 10K resistor.)
R67

271-49.9K (1)
R7 (R2,R3,R9&R11 will be installed later)

271-24.9K (1)
R69

271-1K (3)
R8,R64,R72 (4 more 1K resistors will be installed later: R2',R3',R9',R11')

271-10 (2)
R66,R71

271-10K (2)
R63,R68

271-200K (2)
R5,R73

-----START, OUT+ and OUT- resistor installation -----

271-49.9K (4) (Note: these do not install directly in their position, but instead install just one lead, with the other lead connected to a wire for the individual stage outputs. The lead goes into the hole nearest U2. The "open" lead where the wire is to be installed should be oriented to the right so the designated wire lengths will reach them.)
R2,R3,R9,R11

271-1K (4)
R2',R3',R9',R11' (Note: these install with one leg in the R2,R3,R9&R11 positions, and the other leg attached to a wire that goes to the individual stage outputs. These install into the R2, R3, R9 or R11 hole farthest away from U2. The "open" lead should be oriented to the right so that the designated wire lengths will reach them.)

-----END-----

Insert the following diodes:

78-1N914 (14)
D1,D2,D3,D4,D9,D10,D11,D12,D17,D18,D19,D20,D22,D23 (Be careful when installing as the polarities are not always the same. An easy check is that all pairs criss-cross except pairs D19&D20 and D22&D23. The line for the diode cathode is superimposed on the "N" in 1N914.)

610-1N751A (1)
D21

Insert the following capacitors:

140-XRL25V10 (2)
C1,C2 (long lead to "+" hole)

80-C410C104M5U (14)
C3,C4,C5,C6,C7,C8,C9,C10,C11,C12,C13,C14,C15,C16,C17,C18,C19,C20,C21, C22,C23,C24 (Note to self: C17,C18,C6&C4 not required because U5 and U6 are not populated. C9,C11,C16&C19 are not required because U9 and U10 are not populated.)

Insert the following integrated circuits:

511-TL071CN (1)
U1

511-TL072CN (6)
U2,U3,U4,U7,U8,U11

511-LM336Z (1)
U12 (looks like a transistor)

Insert the following transistors:

625-2N3904 (2)
Q1,Q2

625-2N3906 (2)
Q4,Q3

Solder the following with no-clean solder:

571-6404454 (1)
P5 (no orientation on PCB, the flat retainer clip goes towards the outside PCB edge.

72-T20YP-20K (1)
