Overview

The Peavey 4330174626 is a 25-watt fuse protection bulb designed to sit in the crossover circuit of compatible Peavey speaker cabinets, including the PV115, PV215, TLS-4, and TLM series. Its purpose is simple but critical: the bulb's filament acts as a current limiter that protects high-frequency drivers from being overdriven. When signal levels remain normal, the bulb passes current freely. When excessive power threatens the tweeter or compression driver, the filament's resistance increases and restricts current flow, absorbing the overload before it reaches the driver.

This replacement bulb matches Peavey's original part number 73900689 and uses a T8 shape with end cap bases for a direct snap-in fit. At 1.5 inches in overall length with a C8 single coil axial filament and clear glass envelope, it installs in seconds without soldering or wiring modifications. For anyone servicing or repairing Peavey passive speaker cabinets, keeping a spare on hand is a practical way to avoid downtime from a blown fuse bulb during a live event or rehearsal.
