Receivers, Amplifiers, and Preamps: Tubes or Transistors
Our technicians love tubes and transistor-type equipment! If you have a pair of McIntosh MC40 mono-blocks driven by a C-20 preamplifier or a Sansui 9090DB or a Marantz 2275, we can restore your high-end audio equipment to near-perfect condition. Tube preamplifiers and amplifiers require tube replacements as well as complete electrolytic capacitor replacements. Precise bias adjustments are a must in order to deliver crystal-clean sound. We also use the very best in service chemicals that clean, lubricate, and apply an anti-oxidizing layer for your controls and switches. Many harsh cleaners in the Wild can damage sensitive potentiometer vapor-deposited wafers, therefore we use only Caig Chemical products on all preamp, amplifier, and receiver switches and controls. We invite you to allow our experienced technical staff to restore your unit so that it will provide you with audio enjoyment for many many more years!

Let's Talk About Common Service Issues We See Regularly

Many types of high-end audio use extremely high quality parts, and many of those parts are Military-Spec quality. With this being said (after 30-plus years in the Field), things do break. Class-A operation in many models creates an ultra-low distortion metric for many legacy amplifier brands. This means that the transistors, capacitors, and resistors inside most high-end audio products such as Bryston, McIntosh, Mark Levinson & Perreaux run hot throughout the lifetime of the product. After decades of faithful service, we replace a small number of parts that bring your high-end equipment back to the same-if-not-better operation than when new. Advances in technology make this possible for us to maintain these exacting standards.
