The title says it all; are there books, or more preferably some online sources, that give you all the tube data for each tube. I mean the static anode characteristics graphs for each tube and all the voltages and currents etc.
I have the one's in Aspen Pittman's book and they're pretty good but i don't know how complete/incomplete they are for each valve.
Thanks.

Thanks, i was just wondering if the guys here have books like reference books that have all the popular valves and all their specs in there?
I hear people talking about the 'Receiving Tube Manual' and books like that but i don't even know if those books are in print anymore as they're all really old. :anyone:

Frank's (main site http://www.mif.pg.gda.pl/homepages/frank/vs.html (http://www.mif.pg.gda.pl/homepages/frank/vs.html) ) is much better than RC-30 etc. I have 6 or 8 such dead-tree books (and PDFs). They only show what was top-500 in any given era. They are often just the basic data.
At Frank's, most tube types have several different sheets from different sources. Some short-form, and sometimes a 23-page sheet telling more than you want to know. And all the way back in history up to the last printed pages Frank's friends can find.
Also transmitter, TV-camera, mercury ignitrons, induction-hardening tubes....
Frank's is, I think, my #1 bookmark. (Someone has alphabetized this browser, but usually when I have a new browser the first "Favorite" I store is Frank's.)

PRR Thanks man! i bookmarked that site and it looks like a lot of info on there.
These are the benefits of the internet really aren't they? Whereas before you'd have had to buy a book with tube data in it, now a lot of stuff is more accessible online.
Thanks guys for the help with this as i wondered where to get these data sheets. :grin:

'nother vote for Frank's. Use it all the time.
This one can also be interesting for the occasional obscure tube type (but not a straightforward as Frank's) http://www.r-type.org (http://www.r-type.org)
JJ put their own datasheets up http://www.jj-electronic.com/index.php?option=com_content&task=view&id=15&Itemid=10 (http://www.jj-electronic.com/index.php?option=com_content&task=view&id=15&Itemid=10)
So do New Sensor http://www.newsensor.com/TubeSpecification.aspx (http://www.newsensor.com/TubeSpecification.aspx)
Some info here on Russkies http://www.russiantubes.com/tubes.php?r=12 (http://www.russiantubes.com/tubes.php?r=12)
For some Russian tubes you have to look elsewhere for 'facts' http://www.glowbugs.info/2010/02/6p3-beam-power-tetrode.html (http://www.glowbugs.info/2010/02/6p3-beam-power-tetrode.html) , http://www.tubes.ru/techinfo/HiFiAudio/6p3s.html (http://www.tubes.ru/techinfo/HiFiAudio/6p3s.html) , http://www.jacmusic.com/Sovtek/index.html (http://www.jacmusic.com/Sovtek/index.html)
And there's this place http://www.tubebooks.org/tube_data.htm (http://www.tubebooks.org/tube_data.htm)
And Duncan's http://tdsl.duncanamps.com/tubesearch.php (http://tdsl.duncanamps.com/tubesearch.php)

I usually use the Duncan's Tube Search

This isn't exactly what you are looking for

Another vote for Franks, but I'll add a tip...
If you're bookmarks aren't available, "tubedata.info" is easy to remember, and from that page clicking on the top flag that says "Search tube data" next to it, it will take you to that same page.

More great info guys! Thanks for all these links i'll be checking them all out.
If you're drawing a new load line from scratch and doing it with an online sheet that you've downloaded to your machine how do you do your lines and everything? Do you just use one of those systems like Paintnet or something? or do you just print out a hard copy of the data sheet from your printer and then draw the load lines manually by hand?
See i'm on my laptop and don't have a printer attached up to it so i'd probably need to use Paintnet or that microsoft paint thing.

Merlin did a handy spreadsheet which can draw loadlines for several types of triodes. http://www.freewebs.com/valvewizard2/LoadLinePlotter.xls (http://www.freewebs.com/valvewizard2/LoadLinePlotter.xls)

I hold an index card to the screen, just like when we had books.

>If you're drawing a new load line from scratch and doing it with an online sheet that you've downloaded to your machine how do you do your lines and everything?
Dunno why they made all the pdf's locked but here's my trick:
Pullup the curve sheet you wanna dink with.
Hit ctrl, shift, print screen
Open up PhotoChop, ctrl N enter, ctrl V.
Break out your line tool & calculator and have fun.

I hear people talking about the 'Receiving Tube Manual' and books like that but i don't even know if those books are in print anymore as they're all really old. :anyone:
I've got a RCA Receiving Tube Manual in a paper back form. It's handy for sure, but it has its limitations: my particular revision has later tubes (7189A, 7868, compactrons), but it doesn't have early tubes (80,47, etc), tube data is a summary of the real data, and most listings don't have charts (if they do, they are small without the granularity of the axes marked like the tube datasheet has),, and 75% of the book is comprised of TV tubes or AC/DC tubes... So, if you see one cheap (>$5) at the thift store, buy, otherwise, you aren't missing anything.
online tube data sheets are the way to go...
-
Thanks terminalgs, i saw some copies of these books in online form somewhere but i didn't recognize any of the tubes they were all obscure types that i've never ever seen in a guitar amp so those books might not be very useful for me.
The stuff i've been advised on in this thread id much better for me. :grin:

> why they made all the pdf's locked
Is it really locked PDFs? Reader X in Windoze has "Protected Mode" engaged by default, which sandbags (sandboxes?) a lot of tricks.

I opened two random pdfs in Acrobat Pro. They were both wide open. No security. Which one are you saying is locked
-
Try this one (http://tubedata.tigahost.com/tubedata/sheets/093/6/6BQ5.pdf). It's copy protected, there are many, many more... But easily get around with screen capture tools if all you need is the graphs as already mentioned.
-
Try this one.
Yes, that one from tigahost.com is password protected and only allows printing.
I thought Richard was referring to Frank's site or tubebooks.org.

Tigerhost is a mirror for Frank's. I would say nearly 50% are protected files. Protect against what :dontknow:
