Thought I might straighten this one out a little as the build doc is entirely Distortion+
MXR Distortion+
Resistors:
R1 - 10K
R2 - 1M
R3 - 4K7
R4 - 10K
R5 - 1M
R6 - 1M
R7 - 1M
R8 - 4K7*
Capacitors:
C1 - 1n
C2 - 10n
C3 - 47n
C4 - 1u
C5 - 1n
C6 - 1u
C7 - 47u*
Semiconductors:
IC1 - LM741
D1 - 1N270
D2 - 1N270
D3 - 1N5817*
LED*
Potentiometers:
Volume - A10K
Gain - B1M
* - not in original units, recommended for indicator LED and better power supply filtering
DOD 25O
Resistors:
R1 - 10K
R2 - 1M
R3 - 4K7
R4 - 10K
R5 - 470K
R6 - 22K
R7 - 22K
R8 - 4K7*
Capacitors:
C1 - omit**
C2 - 10n
C3 - 47n
C4 - 4u7 electrolytic
C5 - 1n
C6 - 10u
C7 - 47u*
Semiconductors:
IC1 - LM741
D1 - 1N4148
D2 - 1N4148
D3 - 1N5817*
LED*
Potentiometers:
Volume - A100K
Gain - C500K
* - not in original units, recommended for indicator LED and better power supply filtering
** - some have it, some don't. those that do, have 2n2.
There are other small bits out there depending on the vintage of the 25O in question ... op amps, feedback loop cap in parallel with the 1M resistor, clipping diodes, etc ... there's a table of all this crap floating around the webs that can help should you want to get very era specific.
