Hi everybody,
I am looking for a circuit that modulates the brightness of a single LED somehow proportional to the signal level (preferably taken from the preamp output).. It doesn't have to be accurate at all, this is just for eye candy.
I think they use this type of display a lot on bass amps and i think it must be similar to the clipping indicator circuits you see around here.
Can somebody point me in any direction here?
Thanks in advance!

There's also a LB1443N "vu-meter" IC, 5 LEDs and simpler/cheaper than LM3915/6 circuits. The NAD3020 schematic linked nearby shows how they combine a signal from both speaker channels.
