Fixing a PCB-related issue in a 1960 Infinium requires technical expertise, as you are dealing with high-voltage tube amplification.

It dynamically senses the current flowing through each EL34 tube and adjusts the negative grid bias voltage on the fly.

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.

Unlike vintage amplifiers from the 1960s, the Bugera 1960 Infinium features an onboard digital microcontroller system called .

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.

Enthusiasts and engineers can now explore modifications and customizations, tailoring the amplifier to suit specific musical styles or player preferences.
