Line 24:
Surface mount capacitors of 1206 or 805 are used on the rear of the PCB. See above.
 
For best results, hand match the resistors. This may necesitatenecessitate you buying 100 resistors to sort through.
 
Use IC sockets. Once the unit is assembled, power it, with no inputs connected. Check the voltages at the outputs. Ideally, they will all be at zero. If an output is too far from zero, replace the corresponding chip. (0.083V = a semitone, so 0.005 V would be noticablenoticeable.) That chip can be used in other projects where such an offset is not a problem.
 
If using a boxed header for the power connection, it will need a little filing so it clears the leads of the Ferrite beads.
