IN-13 stereo VU meter, all necessary parts, circuit board and 2 IN13 tubes. You need to have soldering skills and an understanding of electronics. The 12V 0.5A power supply is not included in the price of the kit; you will have to do the finishing work and attach the tubes yourself. This kit creates a great work experience. VU-METER can be used to monitor the output level of a power amplifier. It can also be used as a standalone device,
The circuit is built on a unique K157DA1 chip.
Attention! Be careful, the device has a high voltage of 140V!!! The VU meter module continues to operate at a minimum supply voltage of 9V. You can power the device with a maximum voltage of 12V, but an additional radiator must be installed for the stabilizer. I will send the buyer a complete diagram of the indicator along with the device.
