At Sohns Sound Tech, If it can be fixed, we will!
TeslaAV is a Colorado Springs-based electronics repair business specializing in Hi-Fi, vintage audio, professional audio, loudspeakers, and specialized electronics.
As a Colorado Springs native, my connection to this community and its history runs deep. I began my career interning at Sound Tech Electronics under Brendon Nichols in Knob Hill—just blocks from the site of Nikola Tesla's original Colorado Springs laboratory. That early experience helped shape my passion for electronics, audio, and hands-on repair.
Today, with over 25 years experience, TeslaAV continues that tradition of curiosity, craftsmanship, and practical engineering helping keep good equipment working for years to come.

Loudspeaker Repair & Restoration
We repair loudspeakers across a wide range of applications, including high-end Hi-Fi, vintage stereo, professional audio, PA systems, subwoofers, and car audio. Whether you're dealing with a damaged driver, deteriorated surround, voice-coil problem, crossover failure, or powered-speaker amplifier issue, we'll diagnose the problem and determine the most appropriate repair.
Depending on the speaker and its condition, repairs may include refoaming, reconing, driver and voice-coil repair, crossover component replacement, wiring and terminal repair, and powered-speaker amplifier repair. Our goal is to preserve the performance and character of the original system whenever practical.
Amplifier & Receiver Repair
We repair vintage and modern amplifiers, receivers, integrated amplifiers, preamplifiers, and power amplifiers. Our diagnostic process can include power-supply testing, protection circuits, DC offset and bias measurements, signal-path testing, component-level troubleshooting, and performance testing. From a simple failed component to a complex intermittent fault, we work to identify the underlying problem rather than simply replacing parts and hoping for the best.
Services may include capacitor replacement, power-supply repair, protection-circuit repair, solder-joint repair, bias and DC-offset adjustment, component replacement, and restoration of aging electronics.
Guitar amps/Keyboards and Pro Audio
We repair and service tube and solid-state guitar amplifiers, Keyboards and pro Audio, from vintage classics to modern equipment. Whether you're dealing with no output, distortion, hum, intermittent operation, or other performance issues, we can diagnose the problem and determine the appropriate repair. Our goal is to properly identify the cause of the problem, repair it correctly, and verify the equipment is operating as it should.
Let's Talk About Your Equipment
Have equipment that isn't working correctly or you would like to restore to its full glory? Send us the make and model along with a brief description of the problem. Photos are always helpful for loudspeakers.
We'll review your request and contact you to discuss the next step and arrange a diagnostic evaluation if appropriate.

Tesla in Colorado Springs: Birthplace of Big Ideas
In 1899, Nikola Tesla came to Colorado Springs to pursue some of his most ambitious ideas about electricity, resonance, and wireless power. On Knob Hill, he built an experimental laboratory where he conducted high-voltage, high-frequency experiments, studied electrical resonance and atmospheric electricity, and demonstrated significant wireless electrical effects. His Colorado Springs experiments helped advance his work toward the wireless transmission of electrical energy and influenced his later Wardenclyffe project in New York.
For Colorado Springs, Tesla's work represents an important chapter in the city's history as a place where ambitious ideas in science and technology were put to practical experimentation.
That history also has a personal connection to me.
I am a Colorado Springs native, and my own path into electronics began in the Knob Hill area. Early in my technical career, I worked as an intern at Sound Tech Electronics under Brendon Nichols, just blocks from the historic location of Tesla's Colorado Springs laboratory. What began as an opportunity to learn electronics and repair developed into a 20 year career built around troubleshooting, audio, electronics, and technology integration, and repair with Best Buy and Magnolia HiFi.
Over the years, my experience has expanded across residential and commercial audio/video, professional audio, networking, automation, digital audio, loudspeakers, amplifiers, and vintage electronics. I've worked with systems and technologies including Control4, Savant, Crestron, AMX, Dante, Ruckus, Meraki, and Cisco.
Today, Tesla AV brings that experience back to the fundamentals: understanding why something works, determining why it has stopped working, and restoring it properly.
My focus is specialized electronics repair and restoration, including vintage Hi-Fi, amplifiers, professional audio equipment, loudspeakers, crossovers, and other equipment worth preserving. The goal isn't simply to make a piece of equipment turn on. It is to diagnose the underlying problem, repair it correctly, verify its operation, and preserve the engineering and character that made the equipment worth owning in the first place.
More than a century after Tesla conducted his experiments on Knob Hill, the technology has changed—but the spirit of experimentation, measurement, troubleshooting, and innovation remains.
From Tesla's laboratory to the modern repair bench, Colorado Springs has been part of my journey from the beginning.
Tesla AV is proud to continue that journey through hands-on electronics repair, audio restoration, and technical problem solving right here in Colorado Springs.
