Just bought a matched pair of V-Cap ODAM 0.22uF on Hificollective.
I measured them using my LCR meter DE-5000.
These two capacitors have very different APO On high frequencies.
The first capacitor has:
100KHz - APO=0.015
10KHz - APO=0.000
1KHz - APO=0.000
100Hz - APO=0.000
The second capacitor has:
100KHz - APO=0.129
10KHz - APO=0.013
1KHz - APO=0.001
100Hz - APO=0.000
Looks like a bad quality control. Isn’t it? It looks like the second capacitor has high parasitic inductance.
I already installed these capacitors to my amplifier.
Should I contact to V-cap or Hificollective and ask them for replacement?
Regards,
Alex
