While not "exclusive" in the corporate sense, the of the official Peavey MAX 115 schematic is the key document that has been widely circulated and discussed in online communities. This 7-page PDF is the closest thing to the "master key" for these amplifiers. Because Peavey discontinued the original MAX line, this document has become an invaluable tool for keeping these workhorses alive.
The input stage dictates the tonal footprint of the Max 115. Peavey utilizes a mix of low-noise op-amps (such as the NJM4558 or TL072) and proprietary solid-state emulation tech.
Active/Passive inputs, XLR Direct Out with Ground Lift, 1/8" Aux & Headphone
: Hosts a detailed Bill of Materials (BOM) listing over 150 components, including part numbers for specific resistors, transistors, and ICs. peavey max 115 schematic exclusive

To keep your Peavey Max 115 from ever needing a deep schematic intervention, follow these core preventive maintenance steps: While not "exclusive" in the corporate sense, the
A standout feature in modern Max series schematics, this circuit generates sub-harmonics that trick the human ear into hearing deeper bass frequencies than the 15-inch speaker could naturally produce on its own, all without overloading the power amplifier. 4. The Power Amplifier Stage
This alters the center frequency of the Mid control, shifting the focus from a low-mid growl to a high-mid punch.
: A user reported receiving a rattle when playing a specific note. After tightening all visible screws without success, they contacted Peavey directly. Peavey's customer support provided specific instructions and sent foam tape to repair a grille buzz issue. The input stage dictates the tonal footprint of the Max 115
For any amplifier, the schematic diagram is the blueprint of its electronic soul. It provides a detailed, visual representation of the electrical and electronic components that constitute the amplifier, including the power supply, preamp section, equalization controls, and output stage. The schematic shows the interconnections between resistors, capacitors, transistors, integrated circuits (ICs), and other components, allowing users to trace signal paths and identify potential issues.
: Modern units include a subharmonic generator (Kosmos-C) that adds low-end perception without overtaxing the physical speaker.
In older iterations, this consists of a linear transformer with heavy filtering. In modern Class-D variants, it utilizes a highly efficient Switch-Mode Power Supply (SMPS) providing dual-rail voltages.
