inexpensive passive preamps?
Pro Gold is probably the best kind of cleaner that you can use. It is
around 17 dollars a can, but it is worth it. Pete Jeff Wiseman wrote in message news:ZlPHa.59786$YZ2.221612@rwcrnsc53...

I suppose Radio Shack would sell me some stuff in a can with a little tube. I wonder if the push- Yes, get the spray type cleaner. They also make liquid type cleaners but the spray is far better/easier to use for what you are attempting. It is also not real expensive. button switches and volume / balance controls are sealed, or if I'll find an opening to squirt some contact cleaner in them. The older the unit is, the less likely the controls are sealed (and even "sealed" controls usually aren't water-tight). If I do that, do I just squirt the cleaner, move the control back and forth, and give it a day to dry out before plugging it back in? Well, sorta. Usually by the time you put the cover back on it's all done. The carrier of the solution is some kind of solvent that really penetrates so it evaporates quickly. A few suggestions: 1) Hold the tip of the tube as close as possible to the opening or even inside it if possible. 2) practice a really short blast. Even the better cleaners that come with the adjustable pressure nozzle (like Caig ProGold) tends to have lots of pressure. It's good for getting out the gunk but tend to fly all over the place. I'll usually place my hand or a rag around the area I'm shooting. 3) As you mentioned, moving the control between its limits while the solution is in it will help. 4) the carrier of the soulution usually dissipates within a minute or two. 5) The real trick is usually getting the unit apart far enough to get to the controls to spray them. Be careful of getting spray down in behind any faceplates or you'll have to take things even farther apart in order to clean the residue off of the faceplate. - Jeff |
