The Bugera 1960 Infinium is a high-wattage tube head famously modeled after the classic 1959 "Plexi" circuit, but finding a "cracked" or official schematic can be notoriously difficult due to the proprietary Infinium Valve Life Multiplier technology. While the core audio path remains a fairly faithful recreation of the Marshall 1959 Super Lead, the integration of digital micro-controllers for auto-biasing makes standard repair manuals more complex than their vintage counterparts. Technical Overview & Architecture
Power Amp Section: Utilizes four EL34 power tubes. Unlike vintage amps, the schematic includes the proprietary Infinium circuit, which monitors tube health.
The Bugera 1960 Infinium is a 4x12" closed-back guitar amplifier, boasting a robust 120-watt output and a versatile range of tonal options. With its four EL34 power tubes and four 12AX7 preamp tubes, this amp is designed to deliver a rich, complex sound that's perfect for a wide range of musical styles. The Infinium's proprietary "Infinium" circuit, which includes a unique combination of analog and digital technologies, allows for a high degree of tonal customization and flexibility. bugera 1960 infinium schematic cracked
