Neovibe Question

I'm curious how i would go about getting an LED to pulse in time with the LFO in a Neovibe.  I'm lost as to where i would pull the power from.  I've been looking at the schematic and i can only think that i'd need to pull it from somewhere around D12... this is probably wrong, but thats why i'm asking all you knowledgeable people here =)

Thanks,

Andy

Since the lamp driver is a failure point on these amps, I would replicate the lamp driver transistor circuit in parallel with the existing one and put an LED/resistor in series from the collector to the regulated power supply.

Paralleling the bulb would put more stress on the lamp driver transistor.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

when you say replicate the the lamp driver circuit... how far back in the circuit should i go?


Thanks,

Back to the depth pot wiper.  Or replicate to the wiper of the depth pot but connect to the top of the depth pot.
