[siruis815]

All brand new, never used foil inductors.

Goertz 3.399mH/0.3700R - 12AWG
Goertz 3.405mH/0.3781R - 12AWG
Goertz 3.396mH/0.3755R - 12AWG
Goertz 1.904mH/0.2409R - 12AWG Just for fun I ran a capacitance test - 14.66uF/ESR 0.5818R@120Hz, 0.8337R@1kHz, 1.2R@10kHz
Goertz 0.3310mH/0.1826R 14AWG Just for fun I ran a capacitance test - 1.993uF/ESR 0.2647R@120Hz, 0.5161R@1kHz, 0.9538R@10kHz
Goertz 0.2302mH/0.1261R- 12AWG

Goertz 0.2074mH/0.1227R - 12AWG

Make offers.

I wonder what the self resonant frequency is on those inductors. The ribbon foil may result in a lot in internal capacitance which could result in a low value for that. If it's higher than any frequency that the coil has to deal with, then no problem.

Hm...Thats a good question.

Side note, I updated the listing with actual values from DATS v3. From looking at the response chart, I don't see any wobbles in the inductance curve. Just for fun I tested for capacitance as well. See above.

Bump.

I suggest you attach impedance measurements of inductors to prove there is nothing wrong with them, stray capacitance wise, before you do yourself more damage in regard to this ad.

Manufacturer mentions these have flat inductive reactance between 5 and 50,000Hz. Your capacitance measurement should be flawed.

Your capacitance measurement should be flawed.

Little doubt it is flawed. Just ignore.

Holy hell, if these capacitance measurements were legit, I would have some very poor sounding speakers around the house...

Listing prices would help move these.
