VIC5 "600 mH choke" is Don Gabel's shorted-others (leakage) reading; self-L is 1.26 H (C1) / 1.14 H (C2); k(C1,C2) ≤ ~0.72
- Source — Don Gabel, VIC coil readings workbook (2009–2011), estate VIC transformer (VIC 5), B&K LCR meter, all windings 29 AWG copper.
- READINGS — C1 on core, other windings open: 1262.7 mH @100 Hz, 1218.8 mH @1 kHz. C2 same: 1138 mH @100 Hz, 1093 mH @1 kHz. C1 on core with ALL other windings shorted: 608.6 mH @100 Hz, 600.6 mH @1 kHz (Gabel's leakage-inductance set). DC R: C1 76.7 Ω, C2 70.1 Ω (Fluke). 10 kHz on-core column is n/a or unreliable (near SRF).
- CONCLUSIONS (derived) — (1) The community figure "600 mH per VIC5 choke" is the shorted-others leakage reading, NOT self-inductance. Self-L ≈ 1.26 H / 1.14 H (matches Chris Bake's ~1.2 H / ~1.0 H). (2) Each value is per winding, terminal to terminal; no hidden ×4. (3) Shorting all others dropped C1 to 0.482 of open value → 1−k² ≥ 0.48 → k(C1, any subset incl. C2) ≤ ~0.72. A tight bifilar partner (k≈0.99) would have collapsed C1 to a few %. So C1/C2 are not tightly coupled bifilar partners. (4) Loop L = 1.263 + 1.138 ± 2k√(1.263·1.138): 2.40 H uncoupled; bounded ~0.67 H (opposing, k=0.72) to ~4.1 H (aiding, k=0.72). Settle with series-aiding vs series-opposing LCR test (difference = 4M) at 100 Hz–1 kHz.
