- Here is a video on how to clean Input select switch, Speaker select switch. Volume, Bass, treble & Balance control
May notice a channel cutting out or crackling noise
In this video I will be demostrating on a Pioneer sa 5300 Amplifier
But any make such as Marantz, Sansui, Akai, Sony, Yamaha, Nad, Rotel etc
would be pretty much the same.
Wauw, I've actually had one of those! Really good amplifier that unfortunately got lost during one of my many between country moves.
Glad To See You Back Michael Great Explanation Of Cleaning All The Switches and Pots Not Forgetting The Headphone Socket Your Amp Was Very Dusty I Try And Get Rid Of It With a Soft Brush Before I Clean My Switches And Pots Thanks For The Upload And Hope You Get Settled in To Your New Home Regards mike.
One of the dustist ones I have come across, I just did a quick control clean for a sound check, though looking back now dont know why I did not clean it all at the same time. will get around to a full re-cap on this I think. We have signed contracts and have been told exchange date sould be very soon, so in limbo until then, but a bit of panic packing as also set in lol. Thanks agaim Mike and all the best Michael
These old school open type selectors were always prone to contact issues. Even cheapest sealed relays are more reliable than expensive switches
I just refurbed one of these and replaced all the caps. I don't know why you didn't clean the whole unit out of dust, that stuff is caked all over the unit!
A small air hose or compressor, but just cleaning the pots and faders without removing all the other rubbish in the unit, is kind of half incomplete.
A quick spray of isopropyl all over and blast and rinse the board would also have been helpful.
Each to their own I guess, but you did explain the potentiometers very well, and how they work.
Nice photos too.
Hi and thanks for the comment. Yeh this is one of the worse amps I have had for dust inside.. These were pictures I took quite a while ago now when just quickly cleaning the controls for a channel review. I was going to get back to the soon and do a re-cap and clean with the full video including these pictures. But I had a sub that asked about cleaning the input select switch as they were getting intermintate contact on the phono input on their sa5300, so I quickly put this together for them really, but thought it might help others out on cleaning switches and pots.
@@MichaelYates Ahh I see, that makes sense, Thankyou for the reply back :) For a small little amp, these things sound great in my opinion! Easy to repair, great access to the pcb also. I use mine everyday running my computer audio and turntable through it since bringing it back from the dead, I'm that impressed with it. Maybe it's the big aluminum eye candy knobs I like ahaha!
It is them "big aluminum eye candy knobs" that appeal to lots of people I think
Good tutorial Michael. I did start dust removal with cotton buds but found some soft bristle artist brushes from the pound shop did a much better job ( my top tip of the day ) .
Thanks Simon for leaving the comment and tip
Hi Michael
Just came across your video, thanks very much, it's helped a lot to see how the cleaning has to be done.
I have an Optonica SM- 4646 amp that has a scratchy right channel (left is fine) I think its the selector switch as nothing happens when i twist all the others switches but when I push or pull the selector switch it can induce it or and clear it.
Do you think it's just a good clean that's needed ?
All the best
Terry
Hi Terry, 9 times out of 10 a good given the switch a good clean with some switch cleaner will cure the noise, its only now and then a new switch maybe required.
My Yamaha RN 602 volume knob is not working. I am able to change volume by remote control. What can be the probable causes and solutions for this issue?
Seems the volume pot is on a little board of its own, check from dry joints on its board, any cracks in the board. Could be the control itself so use a meter set on ohms to see if the control changes value as you turn it. check connections from its board to main board. if all that checks out, it could be the IC that controls the volume input from the volume control knob
@@MichaelYates Thank you very much....
Thanks
Thank You very much Mike , all the best Michael
Hi, thanks for your video, a friend has one of these and was using the record player and their speakers started to burn. I understand that can happen if pushing too much power through. They aren't one to rattle their windows so could it have been the speakers were underpowered for the unit, or a fault within the unit?
Sounds like the speakers are not rated high enough. Though it is possible that the unit is passing DC voltage through its outputs. But I would check the speaker ratings first
There are horror stories involving split supply direct coupled amps with all transistors in a STK chip, if a CE short occurs, the woofer gets burned up quickly, in worse cases I've read a Electronics Australia serviceman story about a Sansui amp amp almost seting the speaker on fire.I've had a Realistic STA 130 shit itself on me while playing fullblast, taking out speaker@@MichaelYates
Sir my stereo amp board have lot of moisture dust how to clean board and preamp kit any good suggestion
I would use a toothbrush gently around board to get all the dust off, then use isopropyl alcohol to clean the board. and leave in a warm place like an airing cupboard where the emersion heater is for a day or 2 to dry out, if there is a lot of mositure then maybe in an oven, but I have not tried the oven myself so could be a little risky, I have heard to bring the oven upto around 60c and turn it off and place board inside for a few hours, I would try the few days in a warm place first.
@@MichaelYates thanks a lot 😊
My volume switch on my pioneer amp crackles when you turn the knob
One squirt of cleaner should do the trick, unless the pot is shot which normally is only a small chance of being noisey beyound cleaning.
What switch cleaner do you use
I use Deoxit F5 but that is expensive, though I have also used WD40 Specialist cleaner witch is cheaper
hi this is a poor amp on the money side you can tell there are reel to reel like this
as long as they work it ok my mate had one i had to fix up
hi how are you i have the good a head to put out video's the red tape is coming of by the end of the year
and they are pay some some money up for me as my computer is very old amd 3+ it's that old
going to amd 4 soon and new chip set as well i got to find money for the cpu
to all out there i will do a start up audio on the costs of doing video i can see why audio is taking of now
the cost is a lot lower than video youtube fans out there i have all the audio gear
please you lot you never keep up with me don't try please you look silly

Keeping well thanks Bob, hope your the same, just moved into another house which is causing a few headaches at the moment and also delaying me doing anymore videos. But I hope you do get to do some videos, really looking forward to them. even an old pc should be fine just to upload and do some little editing. all the best Bob
