Passive LED VU meter
High guys!
Anybody who has a design of LED VU meter that don't use IC chips on resitor and zener diode and without using external power supply. it is connected directly to the speaker terminal. I've made this already but unfortunately i've lost the design and forgot the value of the resistors and diode. i need a design for a 20 watt amp. tnx |
