![]() I was running low on all that stuff anyway and am about to place an order with the factory. She also said that for plastic conductive pots and faders, their Fader Lubricant is recommended.įor their tech info pdf on all this, go to. The D110S-2 is actually a little cheaper than Deoxit D5. Both contain a lubricant, but neither contain any solvents. She explained that Deoxit D5 is a weaker solution whose composition includes two or three less ingredients and that it is not harmful to carbon pots, but probably less effective than the D110S-2. She told me that for carbon track pots and faders, they recommend their D110S-2 100% solution Deoxidizer. Today I phoned Caig and went over some of these questions with a very knowledgeable lady in their tech support department. I think I bought a tuner cleaner or a contact cleaner from them a while back, which of course, did not work well on controls. I'll have to see if my local Radio Shack has a control cleaner. They are not really noisy or scratchy sounding, but the bass and/or treble will jump up and down as you turn the control. On the Scott, the volume control works great, but the bass and treble controls are a little scratchy as you turn them. If the control is "worked" a few times, and as the unit heats up, the scratchiness in the control goes away, but then when powering it up cold later, it can be quite scratchy again. ![]() I also have a Heathkit model AA-151 that I have working great, except that the volume pots are scratchy at the low volume end of the controls, which can be annoying. I do not want to risk using the wrong cleaner on my awesome sounding, recapped Scott 299 vintage stereo amp. This is contact cleaner, and not control cleaner, and I think is why I have found when using it on some old radio controls, it helped but not that great, and as was mentioned in this thread, that some "scratchiness" in the control could come back later on, fairly quickly. which was given to me by my uncle, which he got from his job, which is a furnace/oil burner supply business. Right now I have this stuff called Zep Elec. That warm tube sound can usually be overcome by turning up the treble. It is not a quality lubricant designed for carbon film potentiometers or turntable motor bearings. Oily contact cleaner bleeding all over the chassis and circuit boards was considered unprofessional and sloppy. The shaft was not moved at this point as not to scratch the dry carbon element.įinally just a sprits of Channel Master Shield was sprayed into the control and worked in by again exercising the pot from end to end while the control was still warm. The control was warmed and dried with a hand held dryer to evaporate any condensation from the contact cleaner. Spray contact cleaner is cold and causes condensation. The control was exercised from end to end while flushing out all debris. First the pot was flooded with contact cleaner without a lubricant. ![]() We were required to use a 3-step technique to clean controls. When I worked for ABL Electronic Service in the early '80s, we repaired only high end audio equipment.
