Product Overview: The Dukane 1B3250 is a 250-watt audio amplifier designed for public address and intercom systems. It accepts a 1V RMS input signal and delivers up to 70.7V RMS output, suitable for driving distributed speaker systems at multiple impedance taps including 70V, 25V, and 8-ohm configurations. The amplifier features an adjustable input level control and can operate from AC power or a 24V backup supply. It utilizes a dual-stage design with driver and output boards, employing high-power bipolar junction transistors in the output stage for audio amplification in commercial and industrial facility sound systems.

Common Failures
Units received for evaluation have shown issues such as loss of power, blown fuses during power-up, and defective output transistors. Physical damage to components such as solder joints and bent metal parts has been observed in some cases. Other issues have included burned resistors, malfunctioning capacitors, and defective adjustment potentiometers.
Repair Approach
Repairs may involve resoldering suspect connections, replacing defective components such as transistors, sockets, and resistors, and addressing physical deformities. Diagnostic testing is conducted to check the integrity of semiconductors and evaluate voltage levels. In cases of extensive damage, additional time may be required for disassembly and repair of internal components.
Testing & Quality
After repairs, units undergo testing, including diagnostic evaluations, burn-in tests under load, and final output validation. Testing confirms that repaired units operate without distortion and that power outputs meet specified levels. Units are retested to verify that issues have been addressed.
