Hello!
I have started to work slowly with the PDP-11/05 I received a year ago. It
is the big BA11-D chassis type machine. The power supply is now fixed and
working fine. A few smaller capacitors were leaking. But also one of the
big input filtering capacitors was bad and had to be replaced.

Yup, that's a glass-encapsulated multi-layer ceramic cap,
0.1 uF value.
I just acquired an RX01 drive (and an RX8E) for my 8/A system. It wasn't too
painful to get it going, as the RX8E had "only" one bad IC that was easy to
find and I had a spare. Details on the DEC forum at vintage-computer.com.
Then the RX01 started audibly working, but with new-old-stock 3M disk

Hi
My regular shipper didn't accept a packag that weighed over 70 kg and I
had trouble to, easily, find another shipper.
But, if I "lied" and put the package withing limits, the cost would run
in excess of 450 dollars.
So.. perhaps not worth it.

I'm not sure what you're describing. Can you link to a pic of one of these

But in general, nothing lower than 1.0uF in value is likely to be
polarized, and any polarized cap will need to have a polarity marking for
at least one of the leads. Smallest polar cap I've ever seen was a 0.47uF

Easier said than done but a big data solution could be applied to ocr.
Eventually Google 's big data ocr tech will be made available open source
to read pdfs. Until then high quality bitmaps are the logical way to scan,
