they dont always do that - which is actually worse because you need to note the details before you pull the old caps - or go searching for pictures afterwards.

So, after desoldering caps what I got is:
3 died panasonic(probably not) caps, each of them lost half 800 uF of their capacity(Finally got at least LCR-T4), and got high ESR
1 out of 4 Kemet caps died on desoldering, as one output lead desoldered(or what it has done) from the cap too. Other Kemet caps survived and still got good ESR in range from 0.07 to 0.11 and 360-380uF capacity

So from datasheet it says ESR at 100 kHz 20C is 16 mΩ

I think this is would be hard one, as polymers are more wide and more low, so I found only 10mm 1800uf one...

Of course they're fake.

I have never seen Panasonic FL sold to the masses that were genuine, nor are they even manufactured any longer.
