The Peavey MAX 115 (and its successor, the MAX 115 II) is a highly regarded 300-watt bass combo amplifier known for delivering "huge bass tone" through proprietary technology like TransTube® tube emulation and psycho-acoustic low-end enhancement. While "exclusive" in marketing often refers to these patented Peavey designs, technical schematics for this model are generally available through third-party repair databases rather than an "exclusive" official portal.

Step 4: Transistor Biasing If the power amp is dead, pull the output transistors and test them with a multimeter’s diode mode. The schematic will tell you if those transistors are NPN or PNP. Replace in matched pairs. After soldering, use the trimpot (often labeled VR1) to set bias according to the schematic’s exact millivolt reading across R85 and R86—usually between 3mV and 8mV for Class AB operation.
