Vox Continental Organ Oscillator Card Bias Pot:
These are ceramic bias pots not the cheap carbon pots that you can find elswhere.
These are a very important factor in maintaining bias condition so that your dividers divide properly. IE, so that your notes sound right. We reccomend you replace all 12 on your organ. The old carbon bias pots are pretty bad and at this point not very effective as degeneration of the carbon track has been occuring for the last 40 years.
Sold individually or in a set of 12.
