bullet Guitar & Keyboard Amplifier Repair

guitar and keyboard amplifier repairs
Whether its tube or solid state, or any power rating, TSI can fix it, calibrate it and make it work properly.

With today's heavy emphasis on vacuum tubes, we invested the necessary resources to tackle the most difficult tube amplifiers.  Our electrical engineers possess an extensive background in vacuum tube theory and practical applications.  We have been designing tube circuits for audio equipment and other applications for over 25 years.  We designed and fabricated curve tracing equipment to map the characteristics of most common vacuum tubes.  We can match tubes to each other and to the electronics they are intended to run in.  TSI can tailor amplifier sound to satisfy the most critical ear.

If your preference is solid state, TSI is also staffed and equipped to handle all of your guitar, bass, keyboard and PA amp needs.  Whether its conventional bi-polar transistors, MOSFETS switching amps, amps with digital effects or MIDI controlled amps, TSI is staffed and equipped to repair it properly, quickly and at a price you can afford.

In addition to maximizing your amp's performance, we also cater to equipment in need of cosmetic surgery.  We know how quickly your amp/amp head can get beat up.  We offer a cosmetic repair service for ripped vinyl, torn speaker grill cloth, structural cabinet damage, etc.   Bring it in... We'll handle it.

Keyboard Service

Keyboard Repair Service
Dealing with a broken keyboard is different than dealing with a broken guitar or amplifier.  Experience has taught us that keyboards often need special attention as its not as easy to just grab a loaner.  If you use another one, will you be able to run your current sequences?  Will you need to spend hours programming it to work with your other modules?  What sounds come with the new keyboard?  We try to help you avoid questions like this by stocking the necessary parts, such as keys, key contacts, switches, jacks and common electrical components for most keyboards and sound modules.  Our aim is to minimize your down time.

For key and key related failures (one of the most common failure modes in keyboards) we can normally provide 24 hour service.  Our large inventory of parts and extensive library of service documentation help us minimize your equipment down time.  We also carry or have access to a large library of factory preset sound for most keyboards. If you need your keyboard repaired FAST and you need it repaired right, bring it to TSI.
