Amplifier Repairs No sound? Sound cutting out or weak? Controls scratchy? Loud hum? Tone not what it used to be? AM Guitar Repair can fix it!

Alan Morrison has over 25 years experience servicing guitars, amplifiers and other music related equipment. "I grew up around my dad's TV shop and learned how to use a tube tester and soldering iron at a very early age. I received an Electronics Technology degree in the early '80s when tube technology was still part of the curriculum. Besides the technology, being a working musician, I understand tone as well. An amplifier doesn't just need to work. It has to provide the tone you are looking for."

All pricing is subject to vary per repair, and is quoted on a piece by piece basis. All service done by appointment only.

Amplifier Repair and Maintenance

When it comes to amplifier repair, AM Guitar Repair does not discriminate! Service is available on all makes and models of amplifiers, tube or transistor.

$40 minimum bench fee for amplifier repairs payable upon bringing the amplifier in. The non-refundable bench fee, which will apply toward the total price, covers diagnosis and some simple repairs. Below is a short list of amplifier maintenance packages available. Other repairs will be quoted on a case by case basis.

Tube Amp Tune Up

If it's been awhile since your tube amplifier has been serviced, it will most likely benefit from a tune up. High voltage, heat, and age can cause components to change value or fail. If your amplifier seems to have lost tone or power, it needs to be tuned up.

AM Guitar Repair will perform a "tune up" on your tube amp. Single channel "practice amp" $40 + parts. Dual channel combo amp or larger $80 - $120 plus parts. Price will depend on size of amp and condition. This includes the following:

Check all tubes and replace as necessary (Power tubes are replaced with matched sets. Tubes that test good will not be replaced unless requested by customer)
Clean and re-tension tube sockets
Adjust power tube bias
Clean input and output jacks
Clean and check potentiometers (controls) and replace as necessary
Check fuse size and replace if out of spec (safety check)
Check power supply filter capacitors and replace if necessary
Check coupling capacitors and replace as necessary
Check resistors and replace if out of tolerance
Check reverb unit and repair if necessary
Check and clean speaker connections. Tighten if necessary
Clean inside of chassis
Check operation of amplifier

A tune up includes cleaning and checking the most critical parts of your amplifier's circuitry. Tubes and filter capacitors are checked and replaced as needed. Components that have failed or that are no longer in tolerance are replaced.

Transistor Amp Tune Up

Transistor amplifiers are more stable than tube amps, but can still require maintenance. If the controls are scratchy sounding or the sound cuts out, it may just need a "tune up". Single channel practice amp $40 plus parts. Dual channel combo amp and larger $50 - $80 depending on size of amplifier and extent of work.

AM Guitar Repair will perform a "tune up" on your transistor amp. This includes the following:

Clean and check input and output jacks.
Clean and check potentiometers (controls). Replace as necessary
Check fuse size and replace if out of spec
Check reverb unit and repair if necessary
Check and clean speaker connections. Tighten if necessary
Clean inside of chassis
Check operation of amplifier

3 Prong AC Power Cord Conversion

This modification is highly recommended because it is a safety issue. Some older amplifiers are wired with a 2 prong AC power cord, which can be a serious shock hazard. AM Guitar Repair will install a 3 prong grounded cord on your older Fender amp for $50 parts included. Other amplifiers will be quoted on a case by case basis.
