NOS wunderlich detector

[Bob Cofer]

Are there any NOS 2.5 Wunderlich detectors out there?  Although I have been a radio collector since the early 90's, I have never owned a Scott until recently.  By some miracle, I have obtained three in the last two month.  I have discovered I have a whole vein of knowledge I need to acquire.  Two of the radios use the 2.5V Wunderlich tubes.  I have two Tweeters that came with one of the radios, but are not correct for that model.  They are for later models.  In my years of collecting, I have discovered that trading for something desirable, and hard to get, will sometimes shake loose wanted items/parts loose better than cash.  (Although I would gladly pay cash)  I don't know how the value compares.  The tweeters that I have are black and originally had a cover that bolted onto the back of the PM.  I get a reading on the voice coil, and one has a cone repair.  I suspect both will need to be reconned, as the readings were different.  they have the original plugs, but the cord on one of them is open.  I have no idea if this is reasonable, or even possible.  Or would I be better off just selling the tweeters?

Bob - 

Well, what do you need? Regarding the Wunderlich tubes - they almost never go bad, so if you have good ones in the sets you own, you're probably fine. Having 1 spare might be nice, but not critical, you can make a good substitute from a far more available type 55 tube. All that said, there are good 2.5v Wunderlich tubes out there, but they tend to be a bit pricey. 

What would you want for the tweeters? I could use a pair, I have dozens of sets/amps/crossovers that always need matching up with parts, especially tweeters. The Wunderlich tube sets did not have tweeters available at that time, so there isn't a trade in that direction. The AW23 was the first set to have tweeters (the ones you have are probably from a Philly or Phantom in the later 30s).

Let me know what you are looking for, I have a large variety of things here open to trade for parts that help me complete more Scott radios.

Bob - your permanent magnet tweeters each have a 2 pin plug that fit the Scott outboard crossover of 1940-41, part of the optional high fidelity speaker system for the Philharmonic and Phantom Deluxe models.

Your tweeter cones look fine, for the crossover delivers only high frequency audio so there is little cone movement.

If you find you need or want a 2.5 volt Wunderlich tube (blue glass by Acturus), I can supply one - used, tested good and test run in one of my Scotts. This unique tube has two co-plainer grids designed as a push-pull 2nd detector which also provides for AVC from the center tap off the last IF secondary. Used for later 12 tube Scott Allwave Deluxe and the earlier production 15 tube Scott model Fifteen. Note the tube socket has no tube number ,but the socket button is dark red like the base of a Wunderluch tube. Scott used the 2.5 volt version, not the 6 volt version.

Thanks for the info.  I'm just starting to dive into the sets, I'd like at least one spare.  I have a '37 Philharmonic, with no cabinet.  I was planning on making one.  I don't know where you're located, but working in a trade for a cabinet, or tweeters for the '37 is a possibility.  how ever that would have to work to make things equitable.  I sent you a friend request.

Thanks David.  I am just starting to dive into the sets.  I would like to have at least one spare.  I sent you a friend request so we can discuss it.

Accepted! I'm located in central Ohio, a good distance away unfortunately. I may know someone in your area that might have a cabinet available - I will check and let you know.

If I understand you correctly, you meant trading tweeters.  If that is the case, let me know how we should proceed.  Thanks
