The problem? Peavey has historically been protective of their intellectual property. While they are one of the most helpful companies regarding technical support (often emailing PDFs upon request), finding a public, labeled, and exclusive deep-dive schematic is rare. Most online copies are blurry, incomplete third-gen photocopies.
Finding a clear, "exclusive" schematic for the Peavey MAX 115
: While not a full schematic, the official manual detail blocks for the EQ, DDT protection, and I/O routing. Exclusive Circuit Features peavey max 115 schematic exclusive
A heavy-duty bridge rectifier converts the high-voltage AC from the transformer secondary windings into DC.
The amplifier features dual inputs (or a single input with a pad switch) to accommodate both passive and high-output active bass guitars.

Use a multimeter to check the main power rails (+V and -V) for the power amplifier. Problem B: Distortion or Rattling
The Peavey Max 115 is a popular, high-gain bass amplifier known for its powerful sound and durability. While I couldn't find an "exclusive" schematic, I was able to locate a reliable source that provides the amplifier's schematic diagram.
The schematic shows test points TP7 (pre out) and TP8 (pwr in). Install two ¼” jacks here to use the MAX 115 as a standalone preamp or power amp for a modeler. Based on component callouts on the exclusive drawing:
By using this exclusive schematic breakdown, you can confidently navigate the internal landscape of the Peavey Max 115, making diagnostic checks faster, repairs safer, and tone restoration incredibly accurate.
Peavey MAX 115 Schematic: Technical Breakdown and Exclusive Insights
: One repair case reported that "the amp went dead and upon checking, I realised that the bridge rectifier and transistor Q7 (TIP102) has shorted." After replacing them, the transistor blew again. Further inspection revealed that "resistor R53 (10 ohms) has also blown" and that the power IC itself had shorted internally. The amplifier features dual inputs (or a single
