The power tubes generate significant heat, which can weaken solder joints. A common fix is "re-flowing" (re-soldering) the tube socket pins to repair micro-fractures in the solder.
The is widely recognized as a high-value, feature-packed clone of the legendary 1959 Plexi circuit, offering both parallel and cascaded gain modes at an accessible price point . However, due to its complex PCB construction and "Infinium" auto-biasing technology, users sometimes experience frustrating, intermittent noises.
When probing a live or potentially live circuit, keep one hand in your pocket. This prevents an accidental electrical current from traveling through one arm, across your heart, and out the other arm. 5. Finding and Using Schematics Responsibly
If the back LEDs are flashing, the Infinium system is struggling to bias a tube. B. Poor Grounding (Chassis Issues)
Large electrolytic filter capacitors can store hundreds of volts of electricity even weeks after the amplifier has been turned off and unplugged. Use a properly rated discharge tool (a high-wattage resistor attached to an insulated probe grounded to the chassis) to bleed off remaining high voltage. Verify with a digital multimeter that the voltage at the plate and screen pins reads 0V before touching any internal component.
The 1960 Infinium is an all-PCB (printed circuit board) design, departing from the hand-wired tradition of original Plexis to optimize for modern production.
Focus your troubleshooting on the analog sections first. The preamp and power amp audio paths closely mirror classic, public-domain Plexi designs, making them easy to trace even if the digital auto-bias block on your schematic is simplified or unlabelled.
In the power supply section, several high-wattage ceramic resistors run incredibly hot. Because Bugera uses standard PCB mounting, these resistors transfer extreme heat directly to the fiberglass board. Over time, this cooking process can crack the solder joints, resulting in intermittent power loss, severe humming, or complete amplifier muting. Under-Spec’d Filter Capacitors
We all know the struggle—Bugera/Behringer doesn't just hand these out. After hours of tracing the PCB and cross-referencing with classic British 1959 circuits, I’ve finally mapped out the 1960 Infinium service manual details. Key takeaways: The Infinium Circuit:

A damaged component can disrupt the bias or signal path, leading to massive instability. How to Fix/Troubleshoot "Cracked" Issues

For budget-conscious musicians chasing the iconic roar of a 100-watt "Plexi," this 150-watt all-valve head offered an alluring proposition. However, behind its impressive specs and classic aesthetics lies a digital minefield: the search for its service documentation.

For further information on the Bugera 1960 Infinium, including user reviews, specifications, and repair guides, please consult the following resources:
For cracked tube socket joints, clean away the old, brittle lead-free solder using solder wick. Apply fresh, high-quality leaded solder (60/40 or 63/37) along with a liberal amount of electronics flux. Leaded solder handles thermal cycling better than lead-free alternatives.
