Audio servicing and restoration
I provide repair, restoration, and customization services for analog, solid-state, high-end audio and studio equipment.
I can only take on a limited number of jobs, so I must pick and choose the ones that interest me most. More importantly, I only take jobs that I know I can do excellent work on.
Please use the form below to apply for service, and if I am interested in the job, I will be in touch.
About my work: I do not hurry. I do thorough and meticulous work, and this should be considered the cost of engaging my services. Repair work is done so that—ideally—you cannot even tell the piece was worked on. Any visible work-arounds, such as PCB trace repair, are done neatly, and reliably. Upgrades and customizations are done to a high standard, mechanically, electrically and aesthetically. Any parts at risk of failure are replaced with an appropriate equivalent part, or better. I don’t just “make it work”. I like things to last a long time, and this is what motivates me to do electronics.
See work examples at the bottom of this page.
I am interested in repair or restoration work for these types of components:
I specialize in analog solid-state electronics.
- Amplifiers: Solid-State home and professional audio amplifiers. Amplifiers are just my favorite thing to work on, especially nicely made amplifiers.
- Preamplifiers
- Pro Audio and DJ Mixers (Analog)
- Equalizers, crossovers, compressors, and other analog signal processing devices
- Phono preamps
- Microphone preamps
- Speakers **Local drop-off and pickup only in Madison, WI.
- Turntables **Local drop-off and pickup only in Madison, WI.
I do not work on: (Sorry)
- Digital audio devices such as DACs, streamers, audio interfaces or digital mixers.
- Tube electronics
- Class-D or other switching amplifiers
- Synthesizers or musical instruments
- Musical instrument amplifiers
- Digital studio equipment
- Guitar pedals
- Tuners
- Receivers (Because I don’t do tuners.)
- CD players
- Tape decks (I do not miss them, LOL.)
- Any device more digital in nature than analog. I’m not anti-digital audio, it’s just not my expertise.
- Adcom amps and preamps. Sadly, even though I built my business on Adcoms, and I will continue selling circuit board upgrades for them, I have not been making enough money in refurbishing them. Due to the meticulous nature of my work—it’s a 100% bare-chassis restore and re-build—it was taking me way too much time to finish an amplifier, and I was making a pitiful hourly rate doing so. Adcom amps are awesome, and one of the best bargains in all audio history, but there is a ceiling to what I can charge to repair them.
Obsolete parts:
Due to the unavailability of certain semiconductors and other electronic parts, it is possible to reach a dead-end in a repair or restoration, and the unit cannot be fixed. I will make that determination as early in the process as possible. Parts substitutions are often possible, but may require extra billable time in researching their appropriateness to the task, or locating a reliable source of a genuine part.
Upgrades and customizations:
I can install upgraded components such as stepped attenuators, op-amps, capacitors, connectors, etc. I will recommend upgrades when I think there is good value in doing so. Time spent researching custom upgrades is billable.
Rate: $100/hr
1 hour minimum charge for estimates, applicable to the bill.
