- If someone can recommend a technician in Germany who would create the kind of attestation I am looking for, please propose
I don't know if this hurts the rules of this forum, but I could help you out by measuring and comparing the microphone to two other RE20 I have, plus the one you got.
I would measure acoustic frequency response, and impedance vs frequency, to exclude electrical defects.
I'd only ask for small fee, I don't want to make a business out of this.
I am located in Germany. P.m. me if you are interested.

I'm not conversant on the official rules of eBay, but in my opinion the seller should refund your money if you're not happy with it, period.  Aside from personal integrity and ethics, he wants to avoid a negative seller rating from you.

As a private seller you can exclude any warranty and then you are not obliged to take the item back just because the buyer is not happy with it. But if the item is "not as described", which is the case here, even a private seller has to take the item back for a refund. But the buyer has to prove this.

- Of course, my objective is to send back the mic for a refund. But for that I need to prove that the mic is not fully functioning.

OK, let me clarify a few points:

- I send these audio samples to the seller last week. He claims that he doesn't hear a difference, but he was probably listening on his laptop speakers. He said he has access to high quality studio monitors at work and would get back to me once he has listened on them. I haven't heard anything from him yet. But my feeling tells me that it will not be easy to convince him and I'm trying to anticipate what my next step should be.

- Of course, my objective is to send back the mic for a refund. But for that I need to prove that the mic is not fully functioning. That is why I think sending it to an independent microphone technician who provides the attestation that the mic is defective might be a good idea (actually that is what eBay proposed to do). Once I know a good address, I will ask the seller for his agreement on the procedure.

- I don't want to make changes to the microphone myself because then the seller has good reason to claim that I did cause the damage myself.

- I was in contact with Electrovoice/Bosch Germany. I've been told that they cannot provide the kind of attestation I am looking for. If I send the mic to them, they will repair it and send it back. This will not be cheap and I found it somewhat strange, but that's what I have been told.

- If someone can recommend a technician in Germany who would create the kind of attestation I am looking for, please propose.

Hope it clears things up a bit  :)

This microphone does not work like you expect it to do.
In cases like this I usually ask the seller for a reasonable refund, let's say 50%, if I think I can fix it by myself.

Otherwise, I would arrange with the seller to send the microphone back for full refund.
Spending extra money on this does not make sense, except if it were a real bargain.

If the mic is contaminated with deteriorated foam (even the variable D element, the tube behind the capsule), that can be cleaned, and I would give it a shot.
There is not much more you can fix, maybe check the filter cap .56uF.

I am confused now: You don't want to open the mic, but you think you can get someone to test the mic beyond what you were able to do without opening it up?

And you don't want to send the mic to EV, which would be the place to get a definitive answer.

This to me seems like a lot of complicated moves for a simple purchase. 

Is the seller cooperating with you on this? Have you had clear communications with him about your concerns? 
Why not look for a different mic and try to undo the purchase?

The foam in the PL20 is intact. Actually, it looks rather new. Probably it has been replaced, as you say, but damaged or not cleaned properly while doing so.
But if that theory is correct, the technicians at the shop will not notice any abnormality if they only do electrical measurements of the circuit. will they?

The most likely fault with your PL20 are the plastic-foam parts  (#15 and #17 in the pic Klaus posted). The plastic-foam has deteriorated without any exceptions in mics  as old as all PL20's are. Those parts need to be replaced and eventually the diaphragm needs to be cleaned of the foam sticking to it.

This all is not just a simple matter and need to be done by an expert with experience with these mics. For the diagnosis however the mic needs to be opened to be sure. It is possible, that the parts have been replaced, but the diaphragm was not cleaned or some other damage was done.

Although I hear unwanted high-mid frequencies in your PL20 sample, I would not conclude much just because of that. Make sure the people at the music store are experienced with these mics (PL20, RE20), or otherwise look for somebody else to do that. By the way, those parts #15 and #17 are still available from EV.

Thanks for your experience, Klaus.
Yes, I already tried to contact Electrovoice earlier. But they could only offer me to send in the mic for repair which will immediately cost a significant amount.

Probably what I will do is to bring the mic to a workshop at the next large music store. It will cost a small amount to have them  analyzing the mic and making an estimate for the repair job, but then having it black an white I should be on the safe side.
