RCA tube manual
I just found a link on the web to a CD-ROM called the HB-3 RCA Tube Manual. Supposedly, it contains over 7,000 pages from the original RCA manuals. Is anybody familiar with this resource, and is it worth its $75 price tag?

I've got a copy of the original HB-3 manuals, (there's more than one volume) while I did pay $75 for them,but I'm in a job where I've got to have data handy on the most obscure stuff you can imagine. 99% of what's on there..old radio & TV tubes, computer tubes, transmitter tubes,pencil tubes, CRT's, and so forth, aren't stuff you'll typically find in guitar amps. Now if you've got wads of old, weird tubes and want curves & such for your own projects, it might be useful, tho just for identification purposes, the good old GE  
book is cheaper & easier to use, it lists most old industrial tubes and their commercial  
equivalents, if any.  
 
If you want to see the HB-3 pages for most  
commonly used guitar amp tubes (or the Amperex pages, if they are more complete), you can  
see 'em for ABSOLUTELY FREE (of course, I'm not averse to donations...a 4 pack of Murphy's Irish Stout would be welcome..), right here:

Personally, I use the Electronic Universal Vade Mecum a lot more often than I break out the HB-3's...the RCA books have more explicit data on certain individual tubes...like 4 pages of test requirements for 6201's..but the Vade Mecum has loads of European & Russian stuff that RCA doesn't. Of course, it's twice as expensive as that HB-3 disc, too.

Ned: Just wanted to take a minute to say a sincere THANKS! for making such a valuable resource available to all..  
 
..now if someone would just put that old Gibson service manual online. ;-)
