Background & experience:

I've been working on tube amps every since I modified my first Heathkit "Hi-Fi" for guitar use in 1968. I've was an electronics design engineer by profession for 30+ years and have countless hours of experience on everything from vintage tube amps to modern high density printed circuits. I have a well equiped shop with all the tools and instruments required to trouble-shoot and test most audio equipment. Lab Bench

Services:

- Amplifier Maintenance & Repair

I specialize in tube amplifiers but do solid-state as well as. Note: class D devices (& other switching technology) are often not cost effective to repair.

Re-tube & re-cap are common services I can do with very rapid turn around.

Many common tube failures can be addressed within 24hrs.

- Amplifier Modification

Modifications are most common on tube amplifiers. Typical mods include master volume, triode modifications, and tone stack mods. Contact me for consultation and a quote.

- Custom Builds

I have built several amps from kits and from scratch. I will build to spec from kits or from scratch. Contact me for a quote.

- Speaker Repair

In many cases it is not cost effective to rebuild speakers. However, for high-end and vintage models it often is. I can rebuild many JBL, Jensen, Celestion, and Eminence (as well as many other less common) speakers. Contact me for a quote.

- Effects Repair

In many cases it is not cost effective to repair effects. However, for high-end and simple failures it can be. Contact me to discuss failure symptoms.

- Guitar Electronics & Setup

In addition to guitar electronics repair and customization, I am trained and experienced in guitar setup. I do truss-rod, action, intonation, and pickup adjustment as well fret leveling and dressing when needed.

- Pratt-Read Keyboard Refurb

Pratt-Read Keyboard based systhesizers include Moog, Oberheim, Sequential Circuits and others. These older sythesizers often have stuck keys, poor key action, and uneven key height. Bushing replacement, lubrication, and key leveling can return them to like-new condition. I offer this service for about $4/key.

- Equipment Consultation

I offer consultation on amplifier mods (free if mods are done), equipment purchase recommendations (instrument amplification, Public Address, recording, and acoustics). Fees are negotiated when the scope of work is determined. Contact me for a quote.
