Electronics spray cleaner

The most common problem with guitar amplifiers

and other electronics that are making noise or cutting out

or sticking and not working correctly is a simple fix...

I use Radio Shack electronics spray contact cleaner

for most of my basic repairs

in the pictures posted I show the basics you need....

some screw drivers, basic knowledge, paper towels,

electronics spray contact cleaner, and a knife

First I carefully remove the nobs (volume control, tone control, etc...)

I use napkins to mask the area and keep from scratching the surface

Then I carefully spray into the (control} and work in back and forth....

the Best way is to spray directly into the potentiometer

that requires access to the internal chassis

on a quality pot there is a Notch that you want to spray into

on a standard pot just spray....

this will repair any scratchy noise or sound that cuts out

on guitar and bass amplifiers,

also can be applied to many other common basic sound problems



I hope this helps someone out?

Where do I test for break in the Mx15r input cuircut if its not sending

The MX15R has a clean and overdrive channel with a common input. The reverb is between these input channels and the power amplifier. The common link between the two, is the input jack and selector switch which chooses which pre-amp section to use. I would check out this switch and jack as most likely, one of the other is open.

imput plug not picking up guitar and making fuzz noise

Inspect the jack for damage... including solder where it attaches to the circuit board. Common problem when someone trips over a guitar cable. Loop the cable through the handle of the amp to REDUCE the chance of this failure.

I have a Flextone II XL 212 combo. When I mute the strings it's quiet, but when I play there is always a hum/buzz with the note on any voice or preset. I've tried different guitar and cord. It's not a mechanical rattle like a speaker, it's an electronic buzz whenever a note or chord is played. It's especially annoying when you're trying to play clean.

You have analyzed the problem... with the strings muted, the unit is quiet... that means the problem is with the guitar or cable picking up the noise. Move the guitar around near other things to search out the source which is probably magnetic fields... orient the guitar differently to sniff for the source. OFTEN lamp dimmers generate higher frequency components that can couple into the guitar pickups. The problem is fairly common.

You likely are in an area that has magnetic fields. Also you may have the settings on the amp that accentuates the noise. Eliminating this noise, especially at low levels, can be difficult if you have devices like flourescent lights that have magnetic ballasts.

You might also try running a different source into the amp such as a walkman player to verify the audio can be cleanly amplified. If that works, then the amp is OK.
