RE: [TCML] DRSSTC weird waveform behavior

[Justin B <boshjack@xxxxxxxxxxx>]

I just wasn't sure, But I plan to try some adjustable inductors with resistor in parallel with my feedback CT, and try to adjust the phase lead, similar to how Finn did his.  I plan to put the resistor back to 5 ohms and adjust the phase.  But yeah, those squiggles lost most people I sent it to.  Will be fun finding a method to fix that one!
