Increasing LFO Speed

[Bio77]

I wanted to increase the speed of the LFO in a chorus circuit.  What can I change to accomplish this?  This is the circuit I'm working with (Agua Net Chorus).  The faster mod isn't working, I dropped the mod value to 100 pF and still no change from stock. I'm okay to forget about the mod, but I'd like to change a value and squeeze a faster max rate.

My first guess would be to try messing with C23. Tack a 1uF box cap on the back and see if that slows it down.

For faster speed I would use lower value, cca 47nF for C23.

Thanks guys, I'll give that a try.
