Dielectric grease on connection ends

As a word of warning, the DeOxit in the red spray can is about as much as you want to use when dealing with connectors!

This is especially true of tube sockets!!

What can happen is the material can creep and contaminate connections, with the result of loss of performance (especially at higher frequencies). So its best just to clean the connections and then **leave nothing on them**! If a contact enhancer gets on insulators (like are found in audio connections) its usually not good.

So while a dielectric grease can inhibit connections, contact enhancers can short them out. I've seen people ruin equipment by indiscriminate use; be careful!!

Hey Eddy - Try Parts Express.  See link here for a range of Deoxit products including Gold in bottle with brush and spray can.  A bit cheaper than $200 per ounce, it would seem.

By the way, unlike a lot of oxides, copper oxide is just as conductive as copper. :)

Of course, I still use crimp bands and nice speaker connectors anyway.

Best,
