Adapting a potentiometer shaft
I want to change the pot on my amplifier with one from Alps. The
problems is the only Alps pot that matches the dimensions and resistance has a slotted shaft and my amp has a pot with a flattened shaft. Is there a way to adapt a slotted shaft so the knob for the flattened shaft can fit without a problem? |

Drill the original knob and insert a plastic bush salvaged from another suitable knob ??? - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

If the shafts in question are the same diameter, you can easily mill, grind, or file a flat onto the slotted shaft. |

Assuming the diameter is OK, put a shim into the slot, then (with the shaft in a vise) file the flat (so it makes a T with the slot). |

Some of them are IMHO WORSE than Taiwan Alpha who 'second source' most of the popular Alps parts at a lower price. We had negligible problems EVER with Taiwan Alpha. Now, if you want laser trimmed conductive plastic, that's another matter. Can you email me please? Willco. Graham |
