A Blue-Alps volume pot (as fitted to an ARC pre-amp) has become noisey when the knob is operated thru the three minimum notches (all other notches are fine). (1) Could cleaning with a contact-cleaner eliminate this minor problem? Specifically, where would I spray the 'cleaner, on a Blue-Alps? (Wouldn't want to muck-up anything). Or do I need to replace the pot. (2) If I do need to replace the pot, can I use a tranny-based attenuator instead, and how difficult would this mod be? |

Then have a look at No Flash. I've had excellent results on switches and Vpots. Unlike Deoxit. |
Yes, and you can read similar praise for the PEC mentioned above. Do a Search on Tube/DIY. nt, posted on July 10, 2011 at 07:41:40 | |

Once you have it apart, apply grease to the resistive element, and turn it a few times.

If true...kinda makes you wonder about paying $12,000 for a simple design? |
