Servisol Super 10

Product Information

I would be inclined to agree with you, so after seeing this comment I did a little testing to see what the reality is. What lubricant is used in the factory? When the potentiometers are new they have a 'stiffness' to them if that makes sense? Using a DC voltage, I turned it up all the way to 100V and there was no significant conductivity (less than 20µA which is as low as my ammeter measures).

Another USA vendor that has most of these products and links to the MSDS is parts-express.com - search for deoxit. The only difference I found is that the Deoxit is ever so slightly conductive. I sprayed a small amount of each into two bottle caps and then used my ohm meter to measure the resistance. Whereas with the servisol there is more than 1000MΩ resistance with the probes a hairs width apart. My meter doesn't measure any higher than this. I repeated the test with the Servisol Super 40 and got approximately 41µA of current at about 452VDC. So I conclude that they are both pretty darn good with DC and about the same performance as eachother.I repeated this test with my 'big' power supply and I started getting around 35µA of current at about 495VDC. It is hard to predict if a given product will solve a given problem on a given fader. It might ruin it, too. Most products will at least temporarily clear up a "dirty" pot problem, but long-term may be another matter. Pot replacement may be the best choice. My experience with Deoxit generally is that they are good, but can't permanently cure a worn pot. So I guess the super 40 is better in this sense as it will not boil off at high voltages leaving it dry, but it is still conductive so the equipment will malfunction. Unlike Marshall who have the luxury of, in Jim Marshall's words using "off-the-shelf components" which are easily available. A sensible move in their business model in my opinion as I have yet to find a Marshall amplifer that Marshall cannot supply parts for no matter how old it is.

I will first spray a little of each in two bottle caps and test the conductivity, see if there is a difference. Thanks for all the advise. The aim here is to try to extend the life of the existing pots as much as possible. Especially with this mixing desk which I cannot get the pots for anymore. Now the Servisol Super 40 was similar at low voltages but performed better further up. I got exactly the same 25µA at 56VAC, but when I went to 103VAC I was still only drawing 0.96mA. This was a lot better that F5's 80mA!

Has anybody got a can of Deoxit F5 that can send me a pic of the ingredients on the can please see what it actually is?

I increased the voltage again and when I got to 138VAC, the lamp lit up full brightness and was drawing approximately 195mA. Oh dear When probing the faders with the ohm meter they measure the corerect value when moving all the way along using either spray.As for lubrication of electrical components at work we use Rheolube from Nye lubricants.Unfortunately I'm not at work at the moment and can't tell you which version we are actually using. I want to say Reolube 716R but I'm almost 60 and could be having a brain fart. This is an extremely thin grease that we use on the mechanical parts of electronic systems.Think gear trains and bearings for matching networks, sliding and rotating components.I've never used it directly on a pot though.Rheolube though is good where you need something with a little more cling than plain oil. H319 Causes serious eye irritation.H315 Causes skin irritation.H336 May cause drowsiness or dizziness.H411 Toxic to aquatic life with long lasting effects.H222 Extremely flammable aerosol.H304 May be fatal if swallowed and enters airways.H229 Pressurised container: may burst if heated. On delivery you must inspect the goods carefully for damage as Inta Audio is unable to accept responsibility for damage in transit, shortage of delivery or loss of products unless the customer advises Inta Audio of such within three working days from the date of delivery. I do not think slight conductivity of the Deoxit F5 is anything to be worried about as it is still very high resistance, especially as we are only talking about low voltage signals.
