MIDI module for controlling 6 tube amp relays without a display. It has no relays but it has signals for switching the relays for each section: +12V, +5V, Re (Relay switch) and GND. In most cases, only +5V and Re signals (or +12V and Re) should be connected to the relay. More relays can be controlled by each section. Up to 0,5 A of current can be drawn from each section for switching the relays.

It also has no buttons. Any button can be connected according to your application.

The LEDs on the board are for checking purposes. Other LEDs can be connected in parallel. Each of the 6 LEDs lights red for off-state and green for on-state.
