Test Equipment Repair and parts
I offer repair service for various test equipment like audio analyzer, spectrum analyzer, LCR meters, etc.
Audio Precision System One/Two/Portable One:
New for 2019, an A-weighting filter that is fully compatible with the Audio Precision A-weighting filter. This filter is a fraction the size and weight of the stock Audio Precision A-Weighting filter and measures 18 x 24 mm. It is fully compatible with the System One, the System Two, 2700 and the Portable One or ATS-1, and supports the filter auto detect feature of the later System Two.
Class 1 ceramic capacitors that were carefully measured individually are used to ensure consistent, accurate and predictable performance. Each filter is fully tested and guaranteed to meet IEC 61672 A-weighting filter Class 1 tolerance limits.
Cost is US $50 and includes worldwide economy shipping and 1 year warranty. Individual Audio Precision System Two frequency plot against IEC 61672 Class 1 upper and lower tolerance limits will be provided.
