1040 good buddy!

[Buzzsaaw]

Ok.. it's 10-4 but here it's going to be model 1040.

I bought a Lang Radio Enterprise 5 tube radio:
http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT
And Can't seem to find much info on it..

This morning, looking on FleaBack, I find this:
http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWAX:IT

Although, the tube config is a little different but the case is just like my Lang.

Interesting that some radio building company's would buy the same case.

I'm trying to find a little history on the Lang company or for that matter, the Federal Company.

Anyone help me out?

My radio's case is in fair shape. Case is great. Someone changed out the tuning shaft and drilled out the knob to fit snuggly onto the "round" shaft (And I mean SNUG!)

The Dial face is cardboard and has warped over the years especially where it had the dial lamp holder attached at the top. I'll have to back it up with some thicker cardboard or perhaps some wood glued onto the back.

Nice looking case, don't ya think?

Is it ever going to stop raining?

Cute widdle feller. Me likey !

[Buzzsaaw]

Yup.. it is cute.

I'm going to try to keep a running list of all the comapny's that used this case... just in case!

Guess they found a winner and kept using it.

[Sandy G]

Yeah, I have an Admiral that could be its "Double-First Cousin"...Again, as you said, a good design...Why monkey w/it ?

[Buzzsaaw]

Interesting. What model is it? I'll see if I can find the schematic and a pic.

Maybe Admiral made all the chassis's too. (?) (is that chassis or chassiss or chassississ for plural?)

Anyway, thanks for the info...

Your Lang has been retrofitted with 1950's era Magnavox knobs. (I probably have the pinwheel type with set screws that are on the Federal if you want 'em). BTW: Philco built a set in a bakelite cabinet in 1947-48 that looked remarkably similar.

I've been looking on Bama and no fed 1040TB...or lang.

I don't know, but it's fun to investigate. Imagin how hard this would be if we didn't have the good ol' internet.

Those "pinwheel" knobs.. they don't look like the ones in the first link? ( the radio I bought)

Here's a pic of the ones stuck on the front of the Lang1040:


Cool of you to offer some of yours... thanks. Do they look close to these? I'm thinking pinwheel means a radiating spoke type look. These are slightly over 13/16" in diameter at the base.

The circuit will most likely be a hybrid of these:

YUP... Thanks WA2ISE...

You got it on the drawing on the right.. That's the tubes exactly. No .05 caps though... so .. here's the list
.01, .03, .004, .03 and a Ecap with a 30 and 20 mfd in it.. I was going to try to find that Fed brand and also the Admiral and see if one of these had the same stuff in them.

I had to order some caps from Canada and I asked them if they've ever heard of this Lang brand and if they had a SD for it.. I'll let you know..

It's fun looking for this stuff.. and I really enjoy FleeBays huge list of radios to stare at and look up the various model's SD's. These radios are really something!.. ah.. those were the days...

Started cleaning up the case a little and removed the dial cover. I noticed it was crack in one place but when I got it out, there's another spot that's cracking. I may be able to glue it back but thought for the fun of it, to see if I could find a replacement.
Measures overall 3 5/8" X 4 3/16" and the dome that fits in the case hole measures 2 3/4" X 3 5/16.



Over all view

corner 2

I've done some looking around in the Antique links for someone who makes this stuff but couldn't find anything. Now I'm looking not only for the Lang 1040 but the Federal 1040T model.

While I'm posting some pics, I did find some knobs that don't look too bad.. the big ones are a little far fetched though...



Da Big ones!



Little ones



And the original little knobs which quite frankly, don't look too good either!..

Keep playing that good AM music!

Finally, I'm getting back to this little radio.

I found one thing kinda funny and haven't been able to see this in any of the AA5 schematics. On the 12SQ7 tube (Det ckt) the two diodes in the detection ckt are tied together. ie Pin 4 and 5 are tied together. Pin 4 is going to the transformer (IF) and pin 5 is tied to the AGC ckt as per the drawing, but strapped together at the tube socket.

Anyone ever see this?

Many Thanks Guys

Looking at the posting " GE L-600 " by Hi Fi Canada I found my answer in one of the replies he got on his tube placement.

[URL=http://www.nostalgiaair.org/PagesByModel/190/M0008190.pdf [/URL]

I'm not sure the above URL worked.. but it can be seen that pins 4 and 5 on the 12SQ7 are tied together.

This drawing may be closer to what I actually have in the radio minus the multi-band selection scheme in the front end.

Except.. Pin 5 is still tied to the AGC ckt.. and not like that drawing of the GE L-660.

Too bad I can't find a Lang AA5 radio schematic. Puzzles are fun with these old radio ckts.

The Federal radios are covered in Riders and possibly sams. I think all post-war.

[ekimetsok]

Buzzsaw: Your picture is of the Maggie knobs I referred to. Since your Lang is such an odd duck, they might be right, but I can't be positive. The pinwheel type on the similarly styled Federal radio look more like original equipment to me.

[Electronic M]

I had the Federal version (may still have it, but don't know) some one repainted it so the grill was gold (like the dial scale), and it had plain knobs if I remember right.

I never knew that other sets used that cabbinet, interesting.
