1629 magic eye level indicator






I wanted to use these magic eyes I bought off of Ebay some time ago.

I put a signal level indicator circuit on my breadboard.

It was a 1629 magic eye with a 12AX7 driver.

I put my signal generator on the input of the amp and the magic eyes responded to the variation of input signal.

There is also a sensitivity control, which did seem to function as well.

Now to hook it up to a music signal for further evaluation.

Note for "modern" tube amp builders: black insulation on clip leads and ground wires is for working out the basic circuit only.

Not recommended for a final build.
