Vintage Audio Restoration And Service

Austin Stereo services and restores vintage analog audio amplifiers, receivers, and turntables.  

The parts in this photo are the original components that were replaced in the routine restoration process of a typical 1970’s receiver.  These components decay over time, no matter how the unit was used, how it was stored, etc.  This full rebuild approach is the only path we offer for these 40 plus year old receivers and amplifiers.  

We replace all electrolytic capacitors in the amplifier stage, preamp / tone control board, and power supply.  This is often referred to as recapping.  We also replace other components known to fail or degrade over time, including key small signal transistors, and resistors, diodes, etc.  Often as many as 50 to 100 parts or more.  This of course varies by make and model.

 

Some of the other steps in our process:

  • Lamps are replaced and incandescent lamps upgraded to correct warm color LED where possible. 

  • Circuit boards are hand resolderd as needed

  • Relay contacts are burnished

  • All controls and switches are cleaned

  • Power amplifiers are biased and balanced

  • The interior and exterior are detailed

  • Each unit is fully tested.

For turntables, recapping also applies to all direct drive, and many belt drive turntables. In addition, turntable service includes the following:

  • Hand resoldering

  • Cleaning controls and switches

  • Calibrating speed (where applicable)

  • Replacing belts

  • Replacing cables (when necessary)

  • Clean controls and switches  

  • Correcting cartridge mounting

  • Bias and balance tonearm

  • Detail in and out

We do not service speakers.  For speaker service, we suggest TexaSound

The parts we use always meet and more often exceed original specifications.  Each completed restoration includes a full 90 day warranty.
