Servisol Super 10

Product Information

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. I increased the voltage again and when I got to 138VAC, the lamp lit up full brightness and was drawing approximately 195mA. Oh dear

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.

What lubricant is used in the factory? When the potentiometers are new they have a 'stiffness' to them if that makes sense? It is your responsibility to request a return. If you don’t tell us you want to make a return, we don’t know. Once you do tell us, we will do everything we can to action it. At approximately 2mm distance between the probes there is approx. 180MΩ resistance in the deoxit F5. When placing the probes so close that they almost touch it is approximately 172MΩ. I have done a lot of research and narrowed it down to three types of lubricant which are available under many different brand names: 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.

So in my opinion, the Deoxit should only be used up until around 50VAC. Which I guess is fine for audio circuitry, which is exactly what they advertise it is designed for. So again, I kept increasing and I eventually got to 400VAC and could not get the deoxit to boil. This is as high as the power supply will go. In the short term as I stated previously the super 40 seems to be a perfect lubricant for these purposes. I will do half the channels on this mixing desk with Servisol super 40 and the other half with Deoxit F5 and see what the difference is.

Another USA vendor that has most of these products and links to the MSDS is parts-express.com - search for deoxit. 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. I sprayed some deoxit F5 into a bottle cap and connected it to my power supply using two crocodile-clips on the edges of the bottle cap with the metal tips submerged in the liquid, and my ammeter in series to measure any current flow. I also had a 20W lamp in series to protect the power supply. 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. 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).
