Yes, it was pretty dramatic.
No global feedback, SE GM70, 1150v is a little dangerous to starting clipping in caps.
Not so sure this little bit of ringing is important on a sq wave. My Slagle transformers behave similarly to sq waves and they are some of the best opts I've heard to date. I have the leads clipped in right now so it may contribute somewhat at this voltage. Could also be the GM70 tube contributing as well. I might try my copper plates and see what happens.
From what I've heard, ringing sounds harsh and annoying, I don't hear any of this.This is one anomaly we never see in spice.....
The IT gave me some more drive with headroom to spare.
