Power comes from a 15V transformer (connected to AC1-AC2). You can generally use the smallest one available, as average power is quite low. The peak current is about 120mA DC, so a 5VA transformer will be sufficient to power two meter circuits. One 15V output goes to the terminal AC1, the other to AC2.

Analog LED Bar VU Meter - The circuit was designed to work with an audio power amplifier which operated off +18v-0v-18v power rails. The actual voltage used is not too critical except that the feedback is referred to the LED chain which itself is anchored to a +12v rail, hence the separate stabilizer __ Designed by Richard Torrens
