This document analyzes the schematic architecture of the Peavey Max 115 bass amplifier. The unit is historically known for utilizing Peavey’s "_transtube" solid-state technology or modern Class D topology depending on the revision year. This paper dissects the three main stages found in the schematic: The Pre-Amplifier (Op-Amp based), The Power Amplifier (MOSFET/Transistor output), and The Power Supply (Switching vs. Linear). Special attention is paid to Peavey’s proprietary feedback loops and protection circuits.
If you own a Peavey MAX 115 bass combo amp and are facing a repair—whether it’s a dead power section, noisy preamp, or blown output transistors—tracking down the correct schematic is step one. The “exclusive” schematic isn’t a secret, but getting the right version matters. Peavey revised the MAX 115 several times (e.g., original, “II,” “150,” and “USA” versions).
Here’s your exclusive guide to finding the authentic Peavey MAX 115 schematic without getting scammed or stuck with a wrong diagram. peavey max 115 schematic exclusive
The schematic reveals a hybrid topology that is unique to the MAX 115 (not shared with the MAX 110 or 112):
We’ve analyzed over 30 bench repair reports for the MAX 115. Here is where the schematic becomes your best friend: This document analyzes the schematic architecture of the
Before we look at voltages or transistor biasing, we must address the single biggest hurdle in repairing a Peavey Max 115: Peavey revised this amplifier multiple times.
If you search online, you will find several schematics labeled “Peavey Max 115.” Some are for older “black knob” versions. Others are for the “silver stripe” era. A few rare ones are for the export models with different voltage taps. The problem is that using the wrong schematic will lead you down a path of frustration, blown parts, and potential fire hazards.

An exclusive schematic isn’t just about rarity—it’s about accuracy. The correct schematic for your specific revision contains:
Without this exclusive data, a simple capacitor swap can turn into a cascading failure of the driver stage.
