hello,
I haven't heard the fakes. They may well be ' better'. ( they're certainly built better) They may well filter out peaky highs and thicken up or compress the signal just like an original mustard. They may not.
I suspect some kind of difference as the dielectric is different, it looks like mylar, but it's tougher, much tougher.
Paper vs plastic bobbin and paper vs plastic transformer wrap = difference in tone, so i suspect it's the same for capacitance, I'm actually not sure at all.
I'm just the guy that pulled one apart after 20-30? years of people being ripped off and realised quickly that these ebay mustards, the majority of them are fake...and then published the proof.
I'm sure I'm not the first person to realise either, people aren't that guillable for that long a time.
The fakes are covered in epoxy, obviously fresh..the stuff is like steel. The originals are covered in a coating that is going off..relatively soft.
