MOTM-ized Blacet Filthy Filtre

2005-12-21 by Dana Countryman

Howdy,

I purchased a MOTM-ized panel for Blacet's Filthy Filtre from Larry 
Hendry's estate.

I'm getting ready to put the kit together, but it appears that Larry 
modified the original design, adding 4 LED's. Here's the graphic:

Anyone have any idea how to add the LED's into the circuit design??

Help,

I'm not absolutely sure how Larry did this but he might have used the four outputs of the LM3914 to drive LEDs as well as switch the MAX364. The 3914 provides a common at each step and the 364 is a "reverse" control type switch (high = OFF).

Some experimentation is in order unless someone can locate a schematic.
