Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Befaco Trolley Bus Eurorack Synthesizer Module.

Setup and maintenance

  • The 5V rail issue on the Befaco Trolley Bus can be traced to the Hi-Link URB2405LD-20WR3 DC/DC converter, a component crucial for powering 5V-only modules like Euclidean Circles.

    Source
  • It's recommended to not exceed 1.75 amps per IDC ribbon cable for safety, despite them being rated for 2 amps under ideal conditions.

    Source
  • One user found that after chaining five modules, the voltage dropped by about 10%, indicating potential issues with power distribution in daisy chaining setups.

    Source
  • It's advised to distribute the power draw evenly across the two +12V rails to prevent overloading, as each rail is assumed to handle up to 2.5 amps.

    Source
  • Building the Befaco Trolley Bus as a DIY kit allows users to strategically place the power supply for optimal cable length and distribution.

    Source

Features and functionality

  • Unlike some early Eurorack cases, the Befaco Trolley Bus originally includes a 5V rail, which is necessary for certain modules that exclusively require 5V power.

    Source
  • The Befaco Trolley Bus utilizes separate +12V rails with a shared -12V and 5V rail, powered by four regulators, affecting how current should be distributed.

    Source
  • The Trolley Bus boards can't be chained via pin connectors; users might need additional power supplies or bus boards for expanded setups.

    Source
  • The Trolley Bus offers a significant amount of power, making it difficult to overload in cases up to 7U in size.

    Source

Mods and upgrades

  • For users experiencing 5V rail failure, replacing the Hi-Link URB2405LD-20WR3 converter is essential. This requires desoldering the faulty component and soldering a new one.

    Source

User experience

  • One user reported encountering the 5V issue after about a year of use, suggesting that longevity of the component may be a concern for frequent users.

    Source

Build quality

  • Users note that the ribbon cable connectors use a mechanical connection where a bladed pin pierces through the insulation, not soldered, which could impact durability and safety.

    Source
  • The Befaco Trolley Bus is noted for its robust build, but assembling the 28 16-pin power connectors can be labor-intensive for DIY builders.

    Source

Use cases and applications

  • DIY builders appreciate the Trolley Bus for integrating Moog semi-modulars and various DIY modules into a single cohesive setup.

    Source

Value and pricing

  • Assembling the Trolley Bus from a DIY kit is cost-effective, providing substantial power for the price compared to pre-built alternatives.
