[sdiy] Fire bottle ladder filter

[Tim Ressel]

Yo,

Okay, I admit it is one of my more bizarre tangents.
However, my glass-FET ladder seems to kinda work. I
took five 12AU7 and stuck them into the Moog ladder
circuit. I also changed the biasing a bit. It is
acting like a VCF. A little distortion, but hey, its
the first try. I'm using 100V at the top of the
ladder, which is the highest I can go without playing
games with filament supplies.

So next I need to complete the circuit and see how it
all plays together.

Isn't this wierd?? It was a very strange feeling
plugging in those tubes.
