HI All,
Anyone with any advice on how to address push knobs/buttons that stick and end up needing to be pulled out in order to disengage the function? I've got a Marantz 2220 with the high filter, low filter, loudness, and muting push knobs sticking whenever I press them.
Thanks!

But wasn't that crackling a "Natural Sound"??

Have you tried cleaning them?
Usually Deoxit and/or Faderlube and a lot of patient working the buttons get sticky buttons loose enough for me. My experience is with those Harman Kardon tiny buttons.
If spraying the body of the switches inside don't work. I remove the faceplate and see if there are front openings I can squirt into with the face up and hope gravity dribbles in from the front.
I don't know if you want to try this, but some have removed them and soaked switches and/or taken them apart.
Thanks for posting this guide :thmbsp:

Hi,
before the cleaning I had a huge crackling in the right channel, after cleaning with (different then Deoxit) contact spray the crackling is perfectly gone, but after 10 minutes it comes back and 10s later it is back as before? So i assume it is a contact problem, but how do I fix it? Cleaning again and again and again?
Information that can help with the solution:
-The noise is independent of the input, if I use the AUX input, I have the noise, if I use the FM radio I have the noise.
-I have 2 channels per side (Remote and main), the noise is in both(also gone in both after the cleaning)
-I have a Technics SA-101L
-Haven't found any relays, is that possible?
Greetings
Dieter

Thanks Arkay for a well written and informative post! You have inspired me to open up my 1975 H/K 330B and give it a well deserved cleaning to eliminate those annoying crackling sounds. Hopefully all will go according to your well laid out plans.

Thanks for the step by step instructions.
I recently deoxited (?) few small receivers and overall great.
1. Pioneer SX-424 -- Some static and scratchy noise went away but the volume knob still makes some hiss. It was hard to reach as the tuner display board was blocking me from spraying properly. I was not comfortable to completely dismantle this. May be I need to take the tuner board out and try again.
2. Sansui 221 -- Power on/off, input selector, volume, loudness etc... all had static when adjusting. After deoxit, it's smooth, no static on anything.
3. Pioneer SA-550 -- Speakers A had sound coming from one channel only. That got fixed after drowning the push button plastic case with deoxit. Now A set has both channels working great.

My last can of Deoxit lost it's propellant after a year and it was half full. I'll be going back to regular and cheaper contact clearner from Lowes which for my purposes works as well.

Yet another "thank you".
Following your instructions, I just got my Marshall amp working again. It had been on the way out for years, and applications of other products made no improvement. First, the pots got scratchy. Then about 5 years ago, I found if I moved them, the amp would cut out. So, I left them in one position. Finally, the amp stopped working at all.
Now, after a good cleaning with DeoxIT, the pots all work quietly through their full range and the amp's as good as new. I've used many spray cleaners over the last 50 years, and none of them have worked this well. Thanks again!

The stuff made a believer of me tonight. I hand a rather nice old Kenwood integrated amp that some years ago went all muddy and low volume (not actually "scratchy"). Decided tonight to give it a shot with Deox. It quite amazes me that it now works perfectly! So afterwards, I hauled out a couple of others, an old Harmon Kardon, and an old Crown to go through when I've nothing better to do these fall nights. When those are done, there's two Yamahas and four unknowns in boxes sealed for the last 25-30 years. I wouldn't be surprised if Deox brought any or all back to useful life.

Deoxit spray cans have a finite shelf life after which they lose their propellant. I had almost a full can that had lost it's prpellent so today I punched a hole in it and drained the contents into a small glass jar. I haven't used any yet but plan to.

Today I tried the Deoxit I drained from the spray can that had lost it's propellant. Drizzled it from a squeeze bottle down the horizontal attenuator shafts on my Foreplay III preamp. Worked the shafts back and forth a few dozen times and now the crackle is gone. Lesson learned: don't throw away your Deoxit once it's lost it's propellant because it can still be used to clean noisy controls.
Hi all,
This post is great, it's giving me hope for my vintage Sansui amp. One channel is quieter than the other. I've got a Sansui qrx 3000 which has 2ch/synthesiser/surround/hall/phase matrix/discrete choices. I don't know what all that means and I only use 2 speakers! Anyway on 2ch and on discrete one channel is a LOT quieter than the other. On the others it's only a little quieter or lower or muffled take your pick.
sometimes the volume drops a little even on the louder channel. Is this all something a clean will fix?
thanks for any advice.
