Warwick 4 tube/Lafayette D-10 - klondike98 - 08-27-2014
OK folks I need a little advice. Picked up this Warwick Manufacturing Co. 4 tube radio
[Image: https://www.dropbox.com/s/xga17u06lg4mtf8/LafayetteD-10_as_received.jpg?raw=1]
based on the licensing label that says “W. M. Co.” but it looks exactly like the Lafayette D-10 on radiomuseum. Schematics are basically the same except Lafayette has an extra cap (C13). The antenna coil in this is toasted.

Its about 2” long. Would something like this Meissner work: MEISR 14-1026 ANT, BC, ADJ, 4 LUG, 1.7"LONG 1 from Playthings of the Past? The part number on the Lafayette schematic is 1142.
I’ve not had to replace an antenna coil before. Not sure what caused the toasting either, so am still going through it to decide what’s needed. Thanks!!

I had exact same problem with the Emerson I restored for a colleague
Either they used AC Mains as an antenna or a lightening strike did it...not sure. Not even sure how as the cap separating antenna from coil was OK.
Anywho, in my case the other two coils (one was the trap) were OK, and the number of turns is low (about 200) so I rewound it, and I did not do the prettiest of jobs, just put two pieces of cardboard to form a bobbin and wound it.
It worked just fine. Took me maybe 1/2 hr for the whole thing.

Thanks Mike, if I have to rewind it I'll give it a try but hope to find a replacement.

I haven't finished the chassis restoration; still looking for the antenna coil or make the decision to try to rewind but the cabinet is finished. It took some of Kenny's whiskey rayon cloth, a new plastic dial cover (it was flat so easy to replace) and the usual toner/clear/rub-out routine. Its a simple little 4 tuber but sure looks cute on the kitchen counter.

If you don't want to try rewinding your antenna coil, this should work for you:

I'm surprised AES still sells these, with their emphasis on guitar amps for the past several years.

Nice job on the radio Bob. It looks great.

That turned out very nice! If you try the antenna coil that Ron pointed out let us know how it works out.
RE: Warwick 4 tube/Lafayette D-10 - klondike98 - 10-24-2014
Thanks guys. Sure will let you know how it goes although it may be awhile before I get to it.

I finally got back to this little 4 tube Lafayette that had a fried antenna coil. I've installed the AES antenna coil Ron recommended earlier in the thread and am picking up the strong local station although at very low volume. A longer antenna wire may help and I have yet to align which is probably needed with the new coil, but at least its picking up signal. Here's the pic of new coil installed and the old one sitting along side it.

I dealt with this exact same problem in an Emerson. Not sure how one toasts it considering the cap in series was OK, but in any case, I rewound it. Worked fine.

Nice looking job on the cabinet!
RE: Warwick 4 tube/Lafayette D-10 - klondike98 - 06-27-2015
Thanks Crist.
Mike, this one was really weird. After I pulled out the old coil I checked continuity just for kicks and it actually had reasonable ohms on both the primary and secondary. It has a clearly charred area on the coil frame and the wire was loose around the coil frame....
