Exclusive Guide to the Peavey MAX 115 Schematic and Circuitry
The Peavey MAX 115 is a staple in the bass community, known for delivering powerful low-end through a heavy-duty 15-inch speaker. Whether you are troubleshooting a 60-watt legacy model or the modern 300-watt Class D version, understanding the schematic is the first step toward effective repair or modification. Core Technical Architecture
The "exclusive" nature of the MAX 115 design lies in Peavey's proprietary signal processing technologies. The circuit is generally divided into several key stages:
Input Stage: Features dual attenuated inputs for passive or active instruments.
TransTube® Circuitry: A patented solid-state tube emulation that adds harmonic "growl" without actual tubes. EQ & Voicing Section: Includes a three-band EQ ( ±15plus or minus 15
dB) with switchable presets: Punch, Mid-Shift (250Hz/600Hz), and Bright.
Psycho-acoustic Processing: Modern units include a subharmonic generator (Kosmos-C) that adds low-end perception without overtaxing the physical speaker.
Protection: The DDT™ (Distortion Detection Technique) compression circuit prevents power amp clipping to protect the driver. Where to Find Schematics

Let’s break down what you’ll actually see inside an authentic Peavey Max 115 schematic. The amplifier is logically divided into four main sections:
In an era of lightweight Class D amplifiers and DSP modeling, the Peavey Max 115 remains a relevant, repairable tool. It has a soulful, thick bass response that many modern amps lack. Better yet, it was built before the era of surface-mount components and proprietary ICs; almost every part is a standard, off-the-shelf item.
But to keep it singing for another 20 years, you need more than a multimeter and a soldering iron—you need the Peavey Max 115 schematic exclusive. This document is your key to understanding the voltage relationships, signal flow, and safety thresholds of a classic bass combo.
Whether you are troubleshooting a blown output stage, modifying the tone stack, or simply recapping the power supply, do not proceed without the schematic. Seek out the genuine, high-resolution, revision-correct service manual. Your Max 115—and your bass tone—will thank you.
Call to Action: If you’ve successfully repaired or modded your Max 115 using the original schematic, share your experience in the comments below. And remember: Always discharge the filter capacitors before touching any component. High voltage can be deadly.

The Peavey MAX 115 has been produced since the late 1990s. Early models use a discrete power amp with bipolar transistors (e.g., 2N3773 or MJ15024). Later versions switched to integrated Class-D modules (like the Peavey IPR-type output stage). Using the wrong schematic can cause magic smoke, not music.
This is a gray area. Peavey owns the copyright. However, under US copyright law, owners of a physical product have the right to repair. Peavey has publicly stated in service forums that they “encourage the sharing of schematics for discontinued products” but do not authorize commercial resale.
Our exclusive content is a transformative work—annotated, error-corrected, and explained. We are not simply copying Peavey’s internal PDF; we are producing a repair aide for a discontinued amplifier (the original MAX 115 was phased out in 2018).
This report documents the internal architecture of the Peavey MAX 115 power amplifier section, derived from an exclusive service schematic obtained direct from the factory service repository. Unlike consumer-grade block diagrams, this document details the discrete component values for the power supply rail switching, the Class-D output filter, and the preamp equalization network specific to the "TransTube" stage.
