Build Notes
Extra pads have been provided in case you want to double up on diodes in the feedback clipping section. For
1
a fully stock unit, jumper D3 and D4.
The original uses a linear (B) taper for the Gain control, but I prefer an audio (logarithmic) taper here.
2
If you want to exclude this control, jumper pads 1 & 2. I recommend including it because it's out of the circuit if
3
turned all the way down. Extra space has been provided in case you want to use the larger 3386 trimmer.
Prior to February 2017, all versions of the DS-830 schematic had C2 at 39n and the Bass pot at 5kB. C2
2
should instead be 3n9 and the Bass pot should be 25kB.
Additional Part Notes
• Capacitors are shown in nanofarads (n or nF) where appropriate. 1000n = 1uF. Many online suppliers do
not use nanofarads, so you'll often have to look for 0.047uF instead of 47n, 0.0056uF instead of 5n6, etc.
• The PCB layout assumes the use of film capacitors with 5mm lead spacing for all values 1nF through
470nF. I prefer
EPCOS box film
• I recommend using
the board and prevent shorts. If you don't use these, use some electrical tape or cardboard to act as
insulation. The right-angle pots will make direct contact with the solder pads otherwise.
