Once considered a closely guarded blueprint for bass excellence, the Peavey MAX 115 schematic
reveals the engineering secrets behind one of the most versatile combo amps in modern music history. This technical map outlines how Peavey delivers professional-grade power and tone through a sophisticated yet reliable circuit. The Heart of the Machine: Key Components
The schematic details a complex assembly of over 150 components. These include specialized integrated circuits (ICs), resistors, and capacitors designed to maintain signal integrity while handling high power levels. TransTube® Technology : A central highlight of the schematic is the patented TransTube circuitry
. This exclusive design emulates the warm, organic saturation of vacuum tubes using purely solid-state components, providing a "Vintage" voice that is both reliable and lightweight. DDT™ Speaker Protection : The circuit includes a proprietary Distortion Detection Technique (DDT)
. This automatic compression system senses when the power amp is beginning to clip and adjusts the signal to prevent speaker damage and harsh distortion. Psycho-Acoustic Processing : Modern versions of the MAX 115 board incorporate a unique psycho-acoustic low-end enhancement
. This effect uses harmonic synthesis to make the 15-inch speaker sound deeper and fuller without physically taxing the driver. Navigating the Signal Flow
The schematic acts as a guide for how sound travels from your bass to the audience: Preamp Stage
: The journey begins at the active/passive inputs, which adjust the gain structure based on your pickup type. EQ and Voicing
: The signal passes through a 3-band EQ and specialized "Punch," "Mid-Shift," and "Bright" presets. Output Management : For the MAX 115 specifically, the schematic shows an XLR Direct Output
with a ground lift, alongside a built-in tweeter that automatically bypasses when the TransTube gain boost is engaged to preserve a classic overdrive sound. Repair and Availability
While Peavey technically owns the copyright to these designs, schematics for older or discontinued models are often accessible through specialized repair communities. Accessing Documentation
: Full service manuals and circuit diagrams can often be found on platforms like Elektrotanya , where experts share them for maintenance purposes. Service Warning

The Peavey MAX 115 schematic reveals a sophisticated solid-state design centered on high-efficiency power delivery and versatile tone shaping. As a 60-watt to 300-watt (depending on the specific generation) bass combo, its internal architecture is built around Peavey's patented TransTube® technology and the speaker protection system. Equipboard Preamp and Tone Shaping
The input stage of the MAX 115 is designed to handle a wide range of signal levels through attenuated active and passive inputs. TransTube® Circuitry:
This stage utilizes proprietary solid-state components to emulate the harmonic distortion and dynamic response of a tube amplifier. The "TT Boost" switch increases gain to produce a characteristic "growl" without significantly altering the overall output volume. Equalization (EQ):
The schematic incorporates a semi-parametric EQ section. This typically includes a three-band setup (Bass, Middle, Treble) with a dedicated
switch to adjust the center frequency of the middle control, allowing for precise tonal sculpting. Voicing Options:
Many MAX 115 models feature exclusive voicings such as "MAX," "Vintage," and "Modern," which modify the internal EQ curve and gain structure to suit different playing styles. Equipboard Power Amplification and Protection
The power section of the MAX 115 is engineered for reliability under heavy load. DDT™ Speaker Protection: A critical component of the schematic is the Distortion Detection Technique (DDT)
compression circuit. It monitors the power amp's output and automatically reduces gain if clipping is detected, protecting the 15-inch heavy-duty woofer from "square wave" damage. Class D Topology: Newer 300-watt versions of the MAX 115 utilize lightweight
power amp modules. This allows for high power output with minimal heat generation, which is often managed by a dedicated power supply PCB. Psycho-Acoustics: The Peavey MAX 115 is not a disposable amplifier
The circuitry may include a "Psycho-Acoustics" button that adds subharmonic frequencies, creating a perception of deeper bass than the cabinet might physically produce otherwise. Full Compass Systems Connectivity and Maintenance
The schematic layout provides several professional-grade routing options. Direct Out (DI): An XLR balanced output includes a Ground Lift
switch to eliminate hum caused by ground loops when connecting to mixing consoles. Auxiliary and Effects:
The board includes a post-EQ effects loop and specialized inputs for headphones and media players (CD/Aux) for practice sessions. Serviceability:

The MAX 115 schematic reveals several "Peavey-exclusive" technologies that define its sound:
TransTube® Technology: This proprietary tube emulation circuitry mimics the harmonic compression of a tube amp. Engaging the "TT Boost" on the schematic often reveals a bypass for the high-end tweeter to deliver a more authentic, gritty overdrive.
DDT™ Speaker Protection: A critical safety circuit that prevents power amp clipping. The schematic shows a compression loop that automatically reduces gain when the signal reaches dangerous levels, protecting the 15-inch heavy-duty woofer.
Kosmos-C (Psycho-acoustic Enhancement): This subharmonic generator adds perceived low-end depth without physically taxing the speaker. On the circuit board, this is often implemented as a dedicated sub-circuit that generates subharmonic frequencies below the primary signal.
HyperVent™ Technology: Exclusive ported cabinet design that uses internal airflow to maximize the response of the 15-inch speaker. Peavey MAX 115 Bass Combo Amplifier - Bajaao
To find the Peavey MAX 115 schematic, your best resources are specialized service manual repositories and community forums. Because this model has evolved from a 60W unit to the more recent 300W Class D version, ensure the schematic you find matches your specific board assembly number (often 99060580). Where to Find the Schematic

Scribd: Hosts a detailed Bill of Materials (BOM) listing over 150 components, including part numbers for specific resistors, transistors, and ICs.
The Tube Store: Offers a collection of free Peavey schematics, though they focus heavily on older tube models. Key Technical Specs to Keep in Mind
If you are repairing or modding the amp, these proprietary features are central to its design:
TransTube® Technology: Peavey’s patented tube emulation circuitry that provides a gain boost and mimics tube-like growl.
DDT™ Speaker Protection: A built-in compression circuit that prevents clipping and protects the 15-inch heavy-duty woofer from damage.
Psycho-Acoustic Low-End Enhancement: An exclusive design that adds subharmonic frequencies to increase perceived bass without overtaxing the speaker.
Power Differences: Newer models typically deliver 300 watts at 8 ohms using Class D topology, making them significantly lighter (approx. 22kg) than older 60W versions. Common Repair Tips
Cleaning: Many "fuzzy" or crackling sounds are caused by oxidized contacts. Use an electronic contact cleaner on the input jacks and pots.
Solder Joints: Older Peavey units often develop loose or "cold" solder connections over time; checking the board with a magnifying glass is a standard troubleshooting step.
Replacement Parts: Potentiometers are often circuit-board-mounted. If you need a replacement, check the serial number on the metal barrel to ensure the correct linear or audio taper. peavey max-115 sch - service manual - Elektrotanya
