Includes a selectable post-phase inverter master volume, though some technical analyses criticize its single-gang potentiometer implementation. The Infinium Module (Auto-Bias)
The is a 150-watt all-tube amplifier designed as a modern, feature-rich clone of the classic 1959 Marshall Super Lead . While the core audio path follows the "Plexi" archetype, the "Infinium" version introduces complex digital control systems and modified signal routing that differentiate it from vintage hand-wired circuits. Core Circuit Architecture
To understand the schematic, one must first understand the signal path. The 1960 Infinium is loosely based on the Marshall 1959 SLP circuit but features several modern departures.
model adds a proprietary, microprocessor-controlled "Valve Life Multiplier" circuit. Proprietary Design : Users on community forums like Facebook Bugera Groups bugera 1960 infinium schematic cracked
At its heart, the 1960 Infinium is heavily based on the classic 100-watt Marshall Plexi architecture, but Bugera added a few modern engineering twists:
The circuit utilizes a generic Atmel microcontroller to actively monitor the current rushing through the power tubes.
Solid-state diodes handle the rectification, offering a tight, punchy low-end response compared to saggy tube rectifiers. The Infinium Tube Life Multiplier Circuit Core Circuit Architecture To understand the schematic, one
The 1960 Infinium circuit is widely considered a clone of the Marshall 1959 Super Lead
Because the power tubes and preamp tubes are often mounted directly onto the PCB, thermal cycling (heating and cooling) and physical movement can, over time, lead to stress cracks in the board or compromised solder joints, particularly around the tube sockets. Symptoms of a Cracked PCB or Component Failure
The Bugera 1960 Infinium is a highly complex amplifier, boasting an impressive array of features, including four EL34 power tubes, four 12AX7 preamp tubes, and a robust solid-state rectifier. With its versatile four-band EQ, built-in overdrive, and two-channel design, it's no wonder that this amp has become a favorite among professional musicians and serious tone enthusiasts.
