I think that old electrical tape has a purpose. I've seen it a lot in the older radios that I've owned, although my collection pales in comparison to yours. It's always the same black tape, wrapped in the same place, wrapped in the same manner. Another KZbin creator said why they did this, and I forgot why. Perhaps I over analyse things......A LOT! Ha Ha. Have a great Christmas to you and your family and I hope all is great in the up coming year! Thanks for all you do and I look forward to another year of beautiful radios while I restore my Silvertone 701 shortwave broadcast receiver in time to watch "A Christmas Story" even though it's not the one in the movie....Close enough. Take care.

Very nice video and super helpful. I purchased an old Heathkit power supply that the person shipped without screwing the transformer down. Of course it came loose and disconnected from the circuit and tore the paper, etc. I’m going to try to repair it though since I do get continuity. Now have to get some fish paper varnish and do it on a day where my eyes are optimal. Thanks!

I like this project. What’s the source to obtain the OLED ?

The best vintage knob I've seen reproduced? I think without a doubt, I'd have to say the late, great John Holmes's knob, recreated by 'Playmates.Inc' somewhere in California. Very good quality.

It's funny. In building this , I could not get it to oscillate until I added a source resistor to ground. I arbitrarily choose a 10k. Works great. Thanks for the circuit. But that was just the osc by itself. Now I see when connected, the BT is somehow the source resistance and you dont need a source resistor.

Hey Don - I remembered seeing this a while back and finally decided I want to build one. I'll be designing and etching a circuit board for mine using KiCad. I'm wondering if the type of transistor used for Q1 is critical. Does it need to be a BC547C? Or can a different NPN transistor be used? Such as a 2N2222A. Thanks!

Looking good Don, I like the coil method and use it about 90% of the time anymore.

Looking forward to your next video Don, really want to see the e-caps in the box since I've never seen that arrangement before.

One by one, getting there. Nice work Don. :)

Never heard of a Pathe radio before. It must of had some connection with the Pathe company that made movies and newsreels. That company is still in existence I believe.

Looks like you are good to go Don. :)

Great information Don! It’s always a relief when the transformer checks out good.

What if the wires are of different gauges?

Thanx Don for your videos. Is there any chance of improving your 'sound' on your videos? It's coming across quite muted. I would help with the cost, however I don't see a 'donate' ICON on this site as others have???

Thanks Don.

great job

That multimeter is pre yellow season of Fluke!? 😊

Well meaning repair! Thanks for the look.

Greetings Don. great detailed video and nice little radio when complete. I am looking forward to part 2. Best wishes, Vin

Thanks Don. I hate restringing dial cords.

Thanks Don. I don't recall you ever doing a TRF set before. It should be very interesting.

I've used the baking soda / thin superglue technique to instantly bond those pesky broken posts. I've also used RTV in soapy water technique to first make a mold of a good post then move the mold over to the damaged or missing post. I then use thin layers of baking soda & superglue to cast a new post in place. The combination forms an incredibly tough material that you can drill & tap. It works in the restoration of other pieces too, ie., filling in missing pieces of Bakelite.

You should be able to call Sony and get a replacement under "right to repair"

Hey Don, those old brittle plastic repairs can be tricky. On some of those I have repaired in the past I have drilled a hole in the center of both pieces and inserted a brad with the head cut off to add strength before using the epoxy. :)

Nice repair Don.

What's the transmit range in actual use?

In your test, go do not show WHERE the ground lead of the scope is connected to. Can you please tell us where the ground lead of the scope is tested (in each directional test) ?

That rusty thing doesn’t realize how lucky it is to have landed on your bench. Look forward to seeing the restoration.

Since this has a power transformer it would also make a good hi fi am tuner.

Ifoiund spray the cone with aerosol cloth spray adheasive works great

Nice thing about t.r.f. radios is they take digital noise better not having a local oscillator to beat against

What a very nice looking original DRY chassis Don. It looks like a nice TRD candidate for restoration. It should be an easy electrical restoration for you and perform quite well. The speaker is in amazing condition. The cabinet is not a particularly attractive design and is not in good shape, but you will make it better than new!

Nice project Don. It’s great that the speaker and power transformer are good. I hope everything is going well, Rick.

No IF cans , what was it like a crystal radio that amplified the audio signal Save that Malloroy capacitor outer jacket

Good looking radio….should be fun…Larry

Hey Don. Looks like another interesting project you've come up with. Gotta love the old TRF sets. Should be fun to follow along your your journey. :)

Yes! This circuit works with newer led bulbs as well. I also had good luck with a white led on the receive end. Take care!

Excellent circuit Don! Thanks and take care.

Very impressive! Nice demonstration of the waveform. Not many oscillators that can be modulated to 100% without falling off. Great design. 👍

Quality of the sound is astonishing for such a simple circuit. Thanks.

Nice sound indeed Don. Pretty simple build as you mentioned. I'm gonna have to drag out my Talking House transmitter one of these days. I doubt it will come close to the quality of sound that yours puts out. :)

Thank you for sharing this with us. Definitely I'm going to build one.

Nice and simpel circuit. Thank you. Awesome cute radio btw.

Thank you that looks super easy to make, I'm going to give it a go!

Hi, I have a ballast tube radio and calculated 35.5v(diode)+25v+25v+6.3v+6.3v+6.3v+6.3v+6.3v+4.25v(bulb)=121.25Vd which works out perfectly. So used a diode and a 1 ohm resistor and radio seems to power up fine but when I measure the ac voltage on the heaters, like say the the 25L6, it is only around 17 volts. If you divide that by .707, it calculates to about 25volts. So my question is, is that so called, diode modified ac voltage reading low because of the diode factoring in or am I missing something??? Thanks!

This is super cool. You are very talented and it seems like you have an engineering background. It is very interesting to see your work. With that said, I would like to see you restore some more radios. I find it so amazing how you wind transformers from 😮similar gauge wire. I have a 1929 Philco 87 highboy deluxe that may need a transformer rework. I am hoping it doesn’t. Please keep the cool video coming. Perhaps something like my Philco. Thanks

Very interested in this idea with safety capacitors. Peter Pan! Is this a American Set? As there is a Australian Peter Pan too.

A looooot of talking.. but the job is well done. Could have been a 10min video though...
