    Great job! And I really like the Montgomery Ward 62-306 That is one sharp radio.

      Thanks a lot Josh. I can’t wait to get under the chassis and see what condition things are in. Best, Don

      I appreciate it Nelson. Hope to get started on it this week. Best, Don

    Really enjoyed this video, the circuit in this and the other video is so interesting. Can’t wait to see the Wards radio too, that’s a real stunner!

      Good to hear from you Buddy. The Airline looks like fun even with the rust removal that lies ahead. Best, Don

      Hi Don, I really love the way you do things, I might not always post but I’m certainly a loyal follower. :-) It’s really nice to be recognized too.
      Funny thing, after watching your video, I immediately went to eBay to see if I could find a radio like this and darned if I didn’t come across a Airline radio that I snagged up immediately, nothing as cool as what you have though. I thought there would be a million examples of it but interesting, it’s one I haven’t been able to find any info on. A MW Airline 62-1050, a little fake leather cover (I think), metal suitcase battery/ac AM radio.
      Thank you, Buddy

      Buddy, that’s an interesting find. Does it look like it needs a lot of work to get it playing again? Like you, I didn’t see any examples of it online. A keeper for sure. Best, Don

      I don’t think it will be a huge deal. According to the ad, it isn’t working now but looking at the photos, I can’t believe it will be too tough. Looking at the pics it doesn’t look like it’s been touched and appears to still have the original caps. It does have a selenium rectifier that will need attention but other than that, caps and just the general items to check, it looks like fun. I really want to see if I can rehab the case and clean up all the alligator hide looking “substance” on the front and back and wrapped around the case. It’s all intact in the photos so I can’t wait until I receive it to see the actual condition.

      Buddy Martin I know you’ll have fun and have it operational in short order. Best, Don

    Hi Don. Awesome job ! It will go very well with your other shop equipment.
    All my best.

      Thanks Bobby. I can’t wait to test it with the Airline Teledial once I complete the restoration. Best, Don

    Hi. Very interesting and well done project. I was wondering what is the reason that you keep the two ferrite rods separated. Instead of having the two rods bundled together and have only one coil around them? Is there an article from the past on the subject?

    • @RestoreOldRadios
      @RestoreOldRadios  4 года назад

      I was inspired by an old article in Popular Electronics by Art Trauffer and my past experience with stacked VHF antennas to increase gain, so I thought I would give it a try. The article is at: worldradiohistory.com/hd2/IDX-Consumer/Archive-Poptronics-IDX/IDX/60s/67/Poptronics-1967-05-OCR-Page-0036.pdf#search=%22art%20trauffer%22 I played around with the spacing to get the best performance. Thanks again for watching and reaching out. All the best. Don

    Fantastic, thanks for showing the direct-input option. Look forward to seeing the new project. Neat looking radio. Or is that a wireless rotary telephone?

    • @RestoreOldRadios
      @RestoreOldRadios  5 лет назад +2

      Thank you. It’s a late 30's Teledial radio made by Montgomery Ward. I hope to have an introduction video posted soon. Best, Don

    • @FluxCondenser

      Teledial? Aptly named!

    That's a nice circuit Don. Your next project looks like a good one. Don't they call those radios "tele dials" or something like that?

    • @RestoreOldRadios
      @RestoreOldRadios  5 лет назад +1

      Jim, you are correct. It’s a Wards Airline model 62-306 Teledial. I hope to get started on it this week and publish an update. Thanks for watching. Best, Don

    Don, Something came to mind concerning your broadcast band amp.: Should one consider making your circuit a permanent mod to a restoration ---In your opinion could one take a lead from the variable capacitor (tuner) (that normally is that capacitor's output) and place it where your varactor diode is instead ....and in doing so create a natural tuned/tank circuit for that radio (once resonance were obtained)? Also in doing so (post the final/buffer stage), parallel a feedback (maybe using an op amp) to control the loop voltage and it's gain? In doing so, if it were successful might that always be in phase with the tuner selection and eliminate the two adjustments an end user might have to have? By the way, great videos and job you're doing.

      Intriguing ideas and ones worth exploring over the winter months if time permits. Thanks again for watching and sharing your ideas to enhance the design. Best, Don

    Do you did or anyone else no if you can replace a ferrite antenna.,my G.E. Tube radio,I bought this radio on.line ,the ferrite antenna snap somewhere along the line.in.two or three pieces,if I glue it back together,might change how the antenna.works.I looking for idea to save this radio? Anyone.,

    • @RestoreOldRadios
      @RestoreOldRadios  5 лет назад

      Ron - if you still have all the pieces, I would try to put it back together using epoxy then check the reception before searching for a replacement. As far as a source, you may find a compatible used ferrite antenna on eBay. Hope this helps. All the best. Don
