Pyramid PS-26KX regulated power supply Repair Service

Professional diagnostic and board-level repair service for this Pyramid PS-26KX regulated power supply.

The Pyramid PS‑26KX is a 25 A linear regulated DC power supply that uses an LM723 voltage regulator and multiple high‑power series‑pass transistors in parallel to deliver up to 15 V output. Common failure points include the LM723 IC (over‑voltage protection circuitry can trip), the pass transistor array (burnt or overheated junctions), and the input filtering capacitors that may sag under load. First‑check diagnostics should verify the AC input voltage and power cord integrity, measure the regulated output with a calibrated meter while monitoring for sudden drops or over‑voltage trips, and inspect the LM723 pinout and pass transistor junction temperatures for signs of failure.
