I went to a hamfest last weekend and found the Chicago FM Club selling papers from a SK estate to raise funds.  A few caught my eye and I will be scanning them and putting them up for distribution as time becomes available.  The first one follows:

                                                  T H O R D A R S O N

                                 The Complete Transformer Catalog 400-CX
                                        1939 -- SPRING -- SUMMER -- 1939

                                         (Supersedes 400-AX and 400-C)

                                          THORDARSON ELECTRIC MFG. CO.
                                          500 W. HURON ST., CHICAGO, ILL.
                                          Demand "Power by Thordarson"

                     POWER * CHOKES * AUDIO * DRIVER * OUTPUT * MODULATION *

                                    PLATE * FILAMENT * C.H.T. * TRU-FIDELITY


This is a high quality pdf, 15.7 Mb but get it once, print it out or put it on a memory stick and you have a useful transformer/tube/circuit reference.

24 pages:

Excellent. Can I add this with attribution to the collection freely available on bunkerofdoom.com?

Yes certainly, I saw the catalog collection there but did not know how to put anything there.  The more servers the better.  Redundancy is a good thing. 

Tnx 73

Pete Millett pmillett.com has a very good site of these kinds of things as I'm sure you know. Why not drop him a line and invite him to also host? We have an informal +attribution reciprocal agreement. If you are open to the general idea, please mirror content from my side as you please.

There really is no public upload to my site because I cannot watch what people would upload all the time and I try to keep the site family friendly so as not to be forced to exclude youngsters from browsing it.

If a resource has many HTML pages, I use HTTRACK to swipe it automated.

BTW there is a Russian tube manual online that I was able to use HTTRACK to translate and download through babelfish by some sneaky URL-fiddling. Think the Russians would come after me for posting that? I asked, but no one replied, and it's a ham club site I think so I don't want to be so rude.. cityradio.narod.ru

BTW russian CB linears.. Si Bi as they call it:

I notice your 5 call- and you are in IL. What the heck you doin up there with them yankees?

I'm pretty busy right now so I'll try to remember this millett thing but I won't be able to do anything about it right away.  I was originally a 9 because I first got licensed when I was living in the Chicago suburbs where I grew up.  I have a 5 call because I got my general class license not long after my family moved to Mississippi.  I lived all over the South for 20 years then moved back up here but kept the call sign because by then the whole FCC assignment system had changed.  Occasionally I get some guy carping at me about my out of district call sign and my response is always: get rid of the vanity call program, let the FCC do the assigning again, reinstitute the 25 year wait for Extras to get a 1x2 call and then I'll think about trying to get a decent K9 or W9 1x2 call.   But as it is now, anyone who thinks I'm going to voluntarily go through all that vanity b.s. to fight over a few crappy N9 1x2 calls, so his world is happy with me a 9 in 9 Land, is dreaming.
