Product reviewsDouk Audio Magic Eye 6E2 EM87 Preamp Tube Level Indicator VU Meter Driver Board

very good

For what it is it works very well and is easy to set up, I put Male RCA contactor leads on the red and black input cables and connected to a dual RCA connector.
Very good value and comes with 6E2 tube. Would buy again.
Did not need to adjust input level.Read full review...

Well made and attractive board, at a very good price.

Well made and attractive board, complete with a tube, for a price far less than what other vendors are asking for the tube alone.

The unit even comes with an USB-to-circular power connector, such that you can power it from commonly available USB 5 volt power supplies or your computer port.
Having said this, I strongly recommend that you make a separate connector and power the board from its intended 6.3 volts. The voltage difference may not seem much, but it is a 20% lower voltage.

This board is a nice addition to a combo Nixie-Dekatron project I built.Read full review...

Well built and works perfectly

Well constructed device with all components needed to enjoy. End user will need to connect to an audio signal with the included connector but this gives you the ultimate flexibility.
Definitely impressive to everyone who sees it in action.Read full review...
