Yes I completed the chip amps for your dual phase almost at the same time. It works superbly although I have not had the chance to use it on the Basis turntable yet. Thus far I have only tested it driving the motor only and not the platter. What I love about it is that it uses DDS and I can use the Roadrunner to apply speed correction. Still have to find time to set this up.
I wired up my Basis Audio turntable motor with a switch so that I could flip from mains voltage to dual phase. There is a marked improvement in reduction of vibration with dual phase. Everything works perfectly although I have not played around with it that much.
I saw that you posted a reduction in distortion for the Falcon. I guess this applies only to the regular version and not the dual phase version. Correct?

The controller I sent you should already have the modification to it since it is a dual output Eagle controller.
Thank you. Good to know it is updated and that you are always improving your designs. I am an ardent fan of your ingenuity...including my friend in Tokyo!

I just fitted a brand new rega 24v motor to my deck yesterday to use with one of your boards Daniel. Sounds very good- much quieter than the Project 18v motor was.
Could you drop me a link to the BOM, i can't find it anywhere and I have two boards to complete for friends next week.
thanks.

Highlights:
- Sinus and Cosinus Output
- Output xx-22V (adjustable with pot) with standard transformer and high voltage (115/230) with step up
- High Power Output with LM3886
- Adjustable phase shift between the two output phases
- Adjustable speed up ramp
- Adjustable frequence for two steps
- USB Configuration with PC Application (English or German)
- working hour timer

Could these boards be used in conjuntion with more powerful amplifiers/motors by leaving out the LM3886 devices?
I have 30~50W Papst motors that need accurate 3 phase drives.
It's quite straightforward to generate 3 phases from Sine and Cosine signals.
