keep us informed about your research on this phaser. I'm also interested in modding this one. Mine has an issue of uneven phasing. Maybe its because of the LFO.

A quick update on the possible mod-values for the capacitors and their paired resistors the phase stage (all µF except where noted):
One might look up the respective schematics for more changes in the phase stage (Resistors, etc.)

Just noticed that Arion phaser is close to the Boss PH-1r.
