Look for an electronics switch cleaner spray that contains a lubricant. There are a number of brands out there. Any electronics parts supplier should have this. The key is that cleaning these will take a number of tries. Spray teh cleaner into the pots and swtiches and "work" them with the power off. That will work for a short time. Continue to work the controls and respray after a few days to clear out the stuff that the lubricant/cleaner will break down over time. It may take 3 or 4 times to completely loosen and clean out all the dirt etc that has accumulated over the years.

    Please also realize that this may not work if the parts are too far gone. Also, don't just spray. You must turn all the controls and switch the switches many times over and over, Then let the unit sit for a day and do it again, The working of the controls will spread the lubricant and loosen up hte accumulated "crud". This is a common complaint. I probably see 2-5 of these a week.

How do i fix the volume control on musical fidelitys the preamp it makes crackling sound at low end and sound goes right to left . Is there anyway of cleaning the rotary contacts?

I use Nutrol Control Cleaner from MG Chemicals. It can be purchaes at most electronic stores. Sprey a LITTLE bit into each control and rotate them a few times. This usually will clean a volume, tone, and other rotory pots, and most switches, as long as they have some way to get the spray into them. If they are sealed units, then replacement of the control is usually necessary.

Do not use too much spray. Wipe away all excess with a tissue or Q-tip.

Left channel static

I have seen dirty switches or pots cause constant static. I would get some contact cleaner and try spraying it into all switches and pots, and work them to clean the contacts. Also, check to see if there is static in a low-level output such as the one for a tape recorder.

Just got a vintage Onkyo receiver mod # TX-840. I have a very scratchy sound in both A and B right channels on all sources. Figured it was a blob channel HOWEVER this unit has a

Vintage hardware means vintage contacts on all the controls which means oxidation which would cause crackly sound or total silence. Typically, it might be a switch you rarely use, like a Tape Monitor or Mute. It's wise to occasionally (with power OFF) manipulate all manual controls throughput their ranges a number of times to wipe oxides from their contacts. Beyond that a trip to the hifi doctor would be advised.

B & O use CPC for parts and spares. If they don't have one I suggest you contact B & O for advice on what to replace it with, as mains switches are safety parts and should be replaced with the same type where possible.

I have a problem with the Main Output on my Adcom 710 Preamp

Hi am gathering that when it is bypassed (tone) its fine which suggests that the problem is on the treble/bass pots or boards. Try cleaning all the pots with switch cleaner first (open the amp and spray it into the pots them selves through little holes). If not there then Check for a loose wire, and can also tap the boards with back of screwdriver while the amp is playing to listen for dry joints (loose solder and CAUTION for getting a shock also!!)
Pretty sure though on the pots or dry joints.

Best of luck
