Scotchn opposing-bifilar rig: no primary clamp and the FET avalanches, so the CH4 drain plateau is ~66 V (display was 10x low, probe/scope ratio mismatch). Each bifilar winding sees ~1.36 kV; a ~1% A/B imbalance ≈ the ±14 V ring
Scotchn, Discord #neuralstan20-testing 2026-10-05, answering #3491. No diode, snubber or TVS across the primary. He confirms the FQP30N06L (60 V) still runs outside spec on this ri...
