Deoxit

Phasearray

Trying to clean up some old receivers. Was told the scratchy sounds are caused by dirty connections. Am I suppose to use Deoxit or are there any other alternatives.

Also, I spray this stuff on the knobs right and not directly on the circuit board?

I always used Cramolin, maybe deoxit is better ?
I found this discussion on Google http://siber-sonic.com/electronics/caig.html

how do I use either product? I don't want to accidently spray it somewhere I'm not suppose to and fry everything.

I've only used deoxit directly into the pots. I would avoid getting any on the circuit boards.

Gotcha.

I use DeOxit and many times in order to get the best possible job done I've needed to to some disassembly of the unit. Simply pulling the knob off and spraying usually doesn't get it done peoperly. I''m a bit anal so I usually tear things apart to get them cleaned right the first time. Some units you have to do this way others have the scratchy controls more accessable.

Good luck take your time and do it right the first time and a little bit goes along way. You don't need to soak everything with DeOxit. If they are really gummed up do 2-3 smallr applications verses one big drenching.

^^^ my father is the same way but sometimes gets in over his head.

Deoxit is definitely great stuff. I'm not a "full disassembly" type (I broke a switch on an old Kenwood, so I'm more cautious these days), but you will need to get into the pots as best you can. Pulling off the knobs and the faceplate along with any retaining nuts and washers should be enough.

I also recommend keeping Q-tips and an old T-shirt handy for wiping up any overspray from the circuit boards. Do be careful to pick off any stray cotton bits that might snag on solder points.

thanks all, I think I'll go with the q-tip. I guess some spillage onto the circuit board will be unavoidable. Hope I don't kill the amp.

CaiKleen and FaderLube are also handy.

Pretty hard to kill the amp with the spillage of DeOxit. If you get an excess amount let it dry for a few hours. You'll be fine

wow that deoxit did absolutely nothing. .... oh will $10 down the tube. Absolutely soaked a old Sony in it and the left channel that cuts in and out still does the same thing. Soaked an old Realistic in it also and it did not fix the scratchy sound when the bass volume knob is adjusted....

The circuit board didn't seem to mind being sprayed with deoxit. Was really hoping it would fix the almost completely faded left channel of a Kenwood amp...but no luck.

Obviously the problem lies elsewhere. Or, you used way too much DeOxit and saturated all the controls and now you are 'eff'd. . It's not a good thing to over use that stuff. If you "absolutely soaked" everything you may have other problems now!

Why would you spray the circuit board? There are no moving parts on the board. Silly!

The inside of the knobs/switch were very hard to get to. I didn't want to take apart the entire thing(I'd probably forget how to piece it back) so I just sprayed it from the crack at the top of the receiver. Of course there's circuit board all over the place and the roughly 40 degrees spray was pretty difficult to aim.

Im just going to use the rest of the deoxit on my car battery terminal.

I just noticed there is a big red "banned" logo next to ka7niq. How/what happned?

Too much banter between him and Forum members that were ruining most of the threads. That's the polite way of putting it.

Deoxit ate a wart of my dingus in 45 minutes.

I am new to this sort of thing, so I will simply give whatever the benefit of my experince can bring.

Pots get dirty, and De-oxit will clean them. That is all it will do, just clean them. Dirty pots often have "dead" spots on em, and of course the "staticy" sound you are all very aqcuainted with I am certain.

I regulary restore old vintage amps, then sell em, buy some more and etc. I currently have a complete Marantz collection, a wonderful HH Scotty LK-72 tuber, a very rare Pioneer SM83 tube rig, and of course the gratuitous Dynaco ST70 tube amp. Many others, too numerous to mention.

I have used De-oxit hundreds of times, and also Radio Shacks cleaner that I like believe it or not lol. The latter I use first for the intial cleaning and check the amp. Then again if needed and re-check. When the controls are clean and smooth, I use De-oxit to finish with a final little twitch. Always have I been able to clean dirty controls with perfect results. Now controls that have damage are a different story, and that is rare really.

If you have other problems such as a power supply in need of cap work, or a sick output trannie, etc, etc, etc, (it can be a lot of things lol), then simply cleaning the controls will not help of course.

Thanks for letting me join in the converstation and each of you have a wonderful day!

welcome to CP !


Will De-ox make the kobs turn smoother ?
Kinda like grease`n them up ?

Or does it just clean ?

treitz3

In some rare instances, yes. It will help ease the "slide".

It cleans and protects if you get both Deoxit [cleaner / DN5] and Deoxit gold [protector / GN5]. Unless you turn on the unit with out first making sure the Deoxit has completely dried, I have never run across a case where it damaged anything or altered performance.

Phasearray, did you turn the knob [get your mind out of the gutter folks] after you sprayed? This will help to loosen any foreign material.
