Hello Mike,
Here are a few more pictures. My current Bias supply completely bypasses the SoundLAB Bias Supply as I have discovered a minimum of 4 significant shortcommings. My Hear Ye Bias corrects providing an Ultra Low Ripple. See the attached inages comparing the SL to yhe Hear Ye. The Yellow trace is DC, the violet is AC. The scale factors are affected by the voltage dividers and differential probes required to safely make these measurements.
Best Regards,
Paul
