I love the smell of ...
Anyway.
Just unpacked the 6236B power supply from ebay seller zhoefler out of Biberach (how well I know that towne, it's the site of one of Europe's largest biogenetic manufacturing plants ...)
a) it came with an invoice
b) even though the outer shipping box was torn (these things can happen) the inner packacking was intact
c) the inner packaging consisted of foam and a LOT of bubblewrap.
d) the unit had a sticker attached which outlined the shortcomings
e) it worked, no rattling inside, no power supply hum
f) switches etc were right no, no scratching, no strange behavior
=> I would buy from this seller again.
