Phaser rate ramp help!

R.G.

Here's my best interpretation of your modifications to this ramping, voltage to current controlled, vactrol LED driver circuit. 

This thing has definitely taken on a life of it's own!

I deleted the 3M9 resistor between the LFO output and the JFET gates, as well as the bias circuit from the original P-90 circuit.
I didn't think that they were needed in this application.

I added a reference voltage divider for R8 (150K) and for the "Width" control since the original bipolar LFO circuit had the width pot returning to 0 volts.

Am I getting closer?

I searched around and couldn't find much on the parallel resistor for the rate LED but...wouldn't you know it...I found an explanation here:
