The Bugera 1960 Infinium is a popular, budget-friendly tribute to the legendary British Plexi amplifiers of the late 1960s. Packing 150 watts of raw tube power, it delivers classic rock tones at a fraction of the cost of vintage boutique gear.
If an amplifier is dropped, the fiberglass PCB can develop hairline fractures. A cracked trace breaks the electrical pathway. Because the Bugera 1960 uses a double-sided PCB (traces running on both the top and bottom of the board), repairing a crack requires carefully scraping away the protective solder mask and soldering jumper wires across the fracture to restore continuity.

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
If you find physical damage or cracked solder joints inside your Bugera 1960, the repair strategy requires patience and proper soldering technique.
Finding a official schematic can be difficult, as the manufacturer often restricts public release. However, technical analysis reveals the following: Core Circuit The Bugera 1960 Infinium is a popular, budget-friendly
This looks almost identical to a classic Marshall schematic. It features standard plate resistors, coupling capacitors, a tone stack, and a traditional power transformer yielding high plates voltages (often exceeding 450V DC).
The author and this website disclaim any responsibility for the use or misuse of the Bugera 1960 Infinium schematic. Users are advised to exercise caution and follow proper safety protocols when working with electronic equipment. A cracked trace breaks the electrical pathway
A traditional three-band passive EQ (Treble, Middle, Bass) paired with a standard cathode follower driven by the second 12AX7 preamp tube. The Infinium Valve Life Multiplier Circuit
: The auto-bias circuit reads voltage across 4.7 ohm cathode resistors to monitor current and adjusts bias via a set line connected to 470K resistors .
While the electronic schematic (the circuit diagram) is correct, the physical schematic (PCB layout) is flawed.
