CLEANING CONTROLS AND JACKS (INFO)

Does your volume control crackle when you turn it? Do the left and right channels cut out when you turn the controls?
You need to clean the controls. OK-- better disconnect the power before doing so.

Contact cleaner and switch cleaner is NOT suitable for cleaning volume controls! Get your application straight!
Incorrect type of cleaner will strip the lubrication out of a volume control and render your control FUBAR. Contact cleaner MELTS plastic! Using the wrong type of cleaner can DESTROY your controls.
Use ONLY lubricated control cleaner, which is specifically designed to clean rotating mechanical parts. THIS IS NOT CONTACT CLEANER!!!
The correct type of cleaner is sprayed into the control in small amounts, ONE spray. Spray this into both sections (left and right) of the control.
Next, rotate the control back and fourth several times, to distribute the cleaner across the entire surface. Allow the control to dry, and wipe off excess cleaner.

An example of REAL control cleaner is DEOXIT or PRO GOLD, sold by CAIG chemical company. This is not cheap, but it will not harm your expensive equipment.

DO NOT rely on a sales person to recommend the correct type of cleaner, verify it YOURSELF, using the recommendations posted on the cleaner manufacturer's website.
You have been warned.

CLEANING THE HEADPHONE / AUDIO JACKS TO CURE AUDIO CUT OUT AND CRACKLES:
The headphone jack contains switching contacts which disconnect your speakers when you plug the headphones in. However, if these contacts become oxidized or corroded, your left and right speakers may stop functioning.
Spray a small amount of cleaner into the jack. Insert a headphone plug, then pull it out, repeat the insertion several times. This will assist the cleaner, to help clean the contacts inside the headphone jack.
After the contacts have been cleaned, your left and right speaker outputs might function again. Try it.
