If you have a Crown Xti or XTi2 amplifer in need of repair feel free to contact us for help. We see a lot of amplifiers with extensive damage caused by improper repair attempts that cause more damage than a typical failure would cause.Д¬rown XTi complete circuit board assembly removed for serviceД¬rown XTi chassis is basically empty once the PCB assembly is removed Island Amplifier USA is experienced in the repair of ANY brand of linear amplifier, both RF and audio, vacuum tube and solid-state, including ACOM, ALPHA, BTI, Command Technologies, Collins, HEATHKIT, ICOM, KENWOOD, Mentron, National, Ten-Tec, TPL Communications, YAESU and others. It is not recommended to attempt servicing these amplifiers without proper training and documentation as there can be dangerous voltages present including on exposed components even when the amplifier is powered off or unplugged. Additionally with the integrated switch mode power supply and high efficiency controlled output sections any measurements used for testing must be referenced to the appropriate ground or alternative reference point. The Crown Xti amplifiers are universally built upon a design integrated into one uniform circuit board assembly which necessitates different troubleshooting methods to isolate problems. We are equipped and experienced in dealing with these technologies including the rework of surface mount components and the proper repair procedures, calibrations and performance verifications to be made on these newer technologies.ДЄ look at the extensive SMT technology on XTi circuit boards Because of the complexity many times it can be complicated or intimidating for many technicians to tackle these amplifiers. We have extensive experience in troubleshooting and repairing all types of amplifiers including the high efficiency and lightweight designs using switch mode power supplies and extensive control circuits to monitor amplifier operation. Some skill, experience and patience (& luck ) is needed to work on these things. This document assumes you have some experience fixing low power amplifiers.

Many of these problems can be avoided with proper operation and maintenance but there may also be times that a failure means a repair is needed, HOW TO REPAIR and TEST AUDIO POWER AMPS (especially the BIG ones) Author: Florence J Boys E-Mail: fboysuoguelph.ca E-Mail: r. E-Mail:. Explains how to use transistor curves to analyze amplifier operation in terms of operating regions, load lines, operating (Q) points, and biasing. The course compares linear and nonlinear (switching) amplifiers. While their reliability is certainly good, as with all things electronic there will be some failures ranging from simple connection issues to output section or power supply failures that are more complicated to troubleshoot and fix. Covers the effects of gain, bandwidth, and distortion on amplifier performance.
