Building this VU meter is a real pleasure considering that we are building a retro Vacuum Tube device with modern elements (I'm talking primarily about the power supply) that are easily available in today's market. On the other hand, the final effect is surprisingly good. The VU meter is very sensitive, has great dynamics, and the response time is instantaneous. Also, the intensity of the light emitted by these tubes is satisfactory. This VU meter would be a great visual addition to a tube amp.
SAFETY NOTE: Please do not attempt to recreate the experiments shown on this video unless you are familiar with High Voltage Safety Techniques! Direct Current even above 60V maybe lethal, even when the AC supply voltage has been disconnected due to the stored energy in the capacitors. I have no responsibility on any hazards caused by the circuit. Be very careful. This is a humble request.
