This listing is for the triple combination of the Turing Pulses expander, Turing Volts expander, and the Turing Bombe. Bombe is an improved derivative of the "Turing Machine" module by Music Thing Modular. All three come together with power bus cable and mounting screws.

The electronics of the "Bombe" module has several quality and reliability improvements over the original "Turing Machine" design, but performs identically to the traditional Turing Machine. The improvements include:

• Consolidated two PCBs into one, improving reliability and eliminating potential connectivity problems.
• The resettable polyfuses now fully protect the module. In the most recent (Turing MkII) design, the diodes were still vulnerable to being destroyed by power polarity issues.

This unit is newly built and fully tested and calibrated.
