    Contact Cleaner 'type' (on Tivoli radio)

    Hi all, I just bought an old but brand new Tivoli 'Model One' radio (platinum series - yay!). I suspect this thing is near 20 years old. Stations come in and play clearly, but... while I'm still dialing in a station, the audio output can be quite scratchy/noisy. The volume knob works...

    Marantz 1152DC / 1180DC - How do you clean the rotary Tape Monitor Switch

    I have a recently acquired 1152DC Integrated amplifier. I'm cleaning the controls as they are very scratchy and touchy. The tape monitor switch is the most problematic. It looks to be enclosed with some openings and sits right next to a circuit board. Can someone shed light on how best to...

    Leaky DeoxIT F100 Cans

    I have TWO different 2oz cans of DeoxIT D100 that both leak down into the inner rim. It isn’t even from spraying- it leaks out just sitting on the shelf. I know this because I’ll soak it up with a qtip, and a month or so later, it will fill up (~1mm) again. The first can was bought new sometime...

    Volume pot cleaning guide for AU-717

    This week I was wrapping up an AU-717 overhaul and noticed the volume pot was noisy around the 9 o'clock region. My first attempt and fixing it was to turn off the amp and work the pot back and forth through the full range a couple dozen times. This didn't help so I knew I needed to do something...

    Scratchy, Non-Uniform Old Volume Control

    Scratchy, Non-Uniform Old Volume Control We just restored a Fisher 800 (TA-800) receiver. One remaining problem: the volume control exhibits areas of scratchiness and non-linearity. I am aware that there is a spray product called “DEOXIT”, mentioned in these forums. However, I also read a...

    Just watched this on youtube: Should that change anything on how we usually go about cleaning pots with CAIG products?

    Yamaha CR-820 cleaning input select switch and mute button

    I have a CR-820 that I picked up a few weeks ago. I've since replaced the lamps and sprayed the pots with Deoxit/Faderlube. Today I noticed that the Input select switch seems to be dirty, left channel intermittently cuts out on AUX. In the past the mute button has also seemed to stick on one...

    Switches and pots cleaning, first try

    After reading threads from in my case audioKarma member Kale, being amazed about how far he takes the restoration process and recently by Bumpalump I decided I will have to learn this side of the game too. Because I can not just go taking apart mostly unreplaceable potentiometers and switches I...

    MG 404-B or Deoxit D-5 for pots? on an old Heathkit AA1600

    Just picked up a real beauty of an old amp, Heathkit aa1600 for cheap and the only thing wrong with it so far is it's filthy and the pots are hit and miss. Got them fairly even now and listing to the amp they seem stable so I thought I would try cleaning them before replacing them. Looking on...

    Crackle In Volume Knob in Technics sa-200

    Hello all, Before you suggest it, I have used deoxit and cleaned every switch and pot as much as I can. But still around 11 o’clock on the volume dial there is some crackle. This only happens on the right channel. Any suggestions ?

    Weak Right Channel, Only Aux and Tape Inputs

    Hey everyone, I have a Kenwood KR-4070 that I've used for about two years now with no problems but recently I noticed that the right channel is very quiet, but only while running through either the Aux or Tape inputs. The Phono input works flawlessly and has great sound through both L/R...

    MA5100...best way to open for deoxit

    Ok, I am not one of you super technical guys so please bear with me. I did a deoxit on my MA5100 a few years back, did all the switches and pots and it was successful until recently. Now having issues with the switches and volume pot again where I dont have consistent volume on both...

    Pioneer SX-50; Intermittent Power Issues

    My main bedroom stereo is a beautiful 1983 Pioneer SX-50. It sounds incredible, with 50 WPC at 0.007% THD. The only problem with this unit is that it seems to have a dirty power switch, and this problem only occurs when the stereo is "cold", being turned on after a few hours, or the next day...

    Old and troubled mixer with no love and care

    Hi, I just received an old mixer from the eighties that has been stored away in a basement for more than 20 years. It was stored in a flight case and all the pots and faders are "glued" and wont move at all. Of corse I dont use much strength to try to move them since that would totally damage...

    Cleaning sealed pots on Sansui QRX-7001 F-2425 Tone Control board

    Hello audiokarma, First post here. I'm in the process of restoring a Sansui QRX-7001 that I inherited from my late father earlier this year. I didn't even know how to solder when I began in June - by now I've completed two DIY amplifiers and a preamp and have recapped and replaced (some of)...

    An observation about tribal lore for cleaning pots

    The popular opinion is to soak the heck out of the pot with DeOxit, swish the control many times side to side, then rinse to wash out the "gunk". And to be fair, that does seem to work pretty well. I now use a method told to me using the needle version of DeOxit and a more targeted way. The...

    Source of 2285B parts :)

    So when I bought my 2285B, I didn't know it was such a rare beast. I got it done but I had a poor condition balance pot and a volume pot that had a bent shaft. Both are unique to the 2285B and the balance pot has a detent click in the middle. What I found after a significant amount of digging...

    Kenwood KR-1400 issues

    Hello! Just getting into the vintage stereo scene and I picked up a Kenwood KR-1400 Receiver and a Hitachi HT-7a Turntable as a starter setup.

    Cleaner for Volume Control on Luxman Receiver

    I'll be tackling the noisy volume control on my R-115 soon. I'm not sure which DeoxIT product to use - D5 or F5. One says to use on metal controls, one mentions for use on plastic and carbon controls. I really don't know enough about the volume control on these units to decide or if there's a...

    TLDR Deoxit Guide

    Foreword Since Caig Laboratories now have a lot of different products and The Idiot's Guide to Using DeOxit (revisited) is becoming a bit old, I decided to do a shortened version of it with spoilers for those who want more information. Also, I added a definitions part for word underlined and in...
