I've only got the schematic for the PH-03, sorry.

Schematic (put in parts as it is a HUGE one )
PSU
Audio path
Phase stages
Parameters
Switching
The huge thing on the right on the parameters schematic is a MC14007 IC with the pinnumbers..... didn't have on in my software. Everything in this unit is fed with the V+2 (12V) but the LEDs are fed with V+1 (18V). Speed ramps up and down when the speed button is pressed.
Part marked "switch" in "Switching" schematic connects to "Sw" in "Audio path" schematic

Excellent!
Now that's a different way of doing a phase stage! If you select the transistors (or use an array on an IC), you can eliminate differences between stages. I'm going to have a play with that way of doing things. Thanks for posting your tracing!
