Thanks, any possibility of putting it "out there" with Bit Torrent?

Hi, Geoff

I'm seeding now, but it is taking forever.
I'll leave my computer on over night.

No promises - if no joy by tomorrow, I'll pull the plug.

I've never had much luck with bit Torrent.

Ed

You should know that Pete Millett has the HB-3 up on the web as well, at
http://www.pmillett.com/hb-3_tube_manual.htm right now. He has it divided
into individual files for each datasheet, which is a pain if you want to
print them all out but kind of handy if you only want to look one up.

note that the HB-3 is a loose-leaf binder handbook, which RCA sent regular
updates and additions to. Not everybody subscribed to the updates and not
everyone that subscribed to them used them, so you will occasionally find
differences between two HB-3 books. Consequently, it's a really good thing
to have several versious available online.

Pete has a lot of good stuff on his site and doesn't
make you wait or pay for multi-part files. He states that
his version of the HB-3 is not yet complete but I haven't
counted pages, it may be just as complete as the other one
which is a genuine PITA to download.

Ed,

Thanks a million from all us "Boatanchorites and Hollowstaters". This
info was nowhere else on the net that I know of. Invaluable.

However, I should add that the version of the HB-3 at
Pete Millet's site is not complete and is in the form of a
great many PDF's, essentially one for each tube he scanned.
While it certainly is valuable the version at Filefactory is
relatively complete and combines into a single PDF. You
should check the version at Millet's site because it may
have some tubes not included in the Filefactory version (see
Scott Dorsey's comments above).

I have downloaded the three files. Despite they have different filenames, after
de-raring they all have the same contents!

If you do download all 3 parts, keep their names unchanged and put them
in the same directory, then must unRAR programs will assemble the entire
book as one file if you extract the first file.

I put the three files in the same directory and un-rared part 1, so getting a
214 Mbyte file.

My mistake was that I then also un-rared part 2, so getting the same 214 Mbyte
file. And again for part 3.

I now understand I should have only un-rared part 1.

By the way, the rar compression is almost inexistent, because the sum of part1,
part2 and part3 is very close to 214 Mbyte. Probably rar was only used to split
the big file into three smaller files.

Just to double check: first tube is 0Z4A, last tube is 9006.

Yes, that's because the images are already compressed. They use a very high
compression algotrythm, uncompressed the book would be around 3500 megabytes,
instead it's less than 1/10th of that. RAR compression on top of that does
not give you very much savings.

Now, if only there was a way to index it by computer.
