MOTM-310 fine tune range modification– New 02/10/02
Just as with my MOTM-300, I found the fine tune range on my MOTM-310 too wide for
my personal preference. On the unmodified MOTM-300, it is about 11 semitones. I
changed mine to 4 semitones. See
I found the unmodified MOTM-310 fine tune to have a range of 8 semitones. I wanted to change that to approximately match my modified MOTM-300 range of 4 semitones.
The change is again simple (although applied differently than the MOTM-300).
You have two easy choices:
The resistor addition is very near the tempco resistor. Here are links to the photos:
This modification is easily reversible. You can restore the cut trace by soldering
a resistor lead between the two via holes where we are installing the 4.7 Meg-ohm
