You should see if anyone wants the vacuum tube if it's working. I can understand not wanting to see the old devices since high voltage is very dangerous and most folks don't have the necessary equipment like an isolated power supply to bring up the vacuum tube system up slowly to ensure everything is working. Plus, you got the issue with potential failure points like the power transformer which often can't be replaced so you're forced to do bodge work (again very dangerous when powered up after an attempted fix) and other parts like the IF transformers (not as dangerous but a real pain to get right, see MrCarlson's lab restoration videos for how complicated it can be.

when I was 12, I opened up a radio like this one which my grandfather bought from UK back in 1980s. It was made out of plastic powered by a 6V lead acid battery. Components were quite different back then. There were expensive Germanium transistors along with chunky electrolytic capacitors and 1W brown coloured resistors. Only same component I found there which we still use commercially is the knob potentiometer. It all were connected by wires, no modern pcb whatsoever. However back then, I didn t know a lot about electronics so I just scrapped the parts and collected them in a jar which I still have. This video makes me feel nostalgic.

Interesting cool little project. Though I'm not sure how I feel about trashing a vintage tube radio. I personally would have restored the old radio part so you could dial in some radio stations the old way (if/when WiFi isn't available. Then integrated the WiFi radio along with a DAB and Bluetooth/BT device into the cabinet along with the touch screen. I'm working on a project of adding bluetooth/BT to the amplifier of my separates HiFi system by upcycling a broken BT headphones set, the physical headset frame and ear cups are broken but the electronics are still in perfect condition.

I really like re-using the old style cabinet. A couple of comments though. Did you really need the AC supply? Could you just have used a USB-C PD board and left the AC part to the external power supply? The touch screen module seemed awfully complex and I assume, pricey. Is there a reason you used it and not maybe a cheaper esp32 with a screen? (edit: actually, looking at mouser, the screen was surprisingly cheap, atleast for that size. Could the touchscreen have been mounted and designed like the old frequency chart in the middle of the radio body, between the dials?

I usually like your projects. Still, this one is hard on me. I love the appeal of those tube type radios, and part of it is their distinctive scent when they get warm. You lost this part to the trash can. Another point is, that musicians spend amounts of money for a tube type amplifier which you had at hand. The only thing you needed, is a Bluetooth to FM converter, and you could have simply played whatever your smartphone throws at the old steam horse. No need for such an invasive solution. Sometimes, less is more.

Perfect opposite of what I like to do. I like the MWL (More with less) Principle. I would have taken a cheap mobile phone and a cheap Bluetooth Speaker. but hey doesn't make for good tube content. I still like your vids quite a lot. Good quality and a lot of information. Btw. what an average STM chip brings is just great. The IDE is Eclipse based so nothing to scream hooray about. Platform IO performs much better for me developing for a little TTGO than Arduino. But I haven't tried it with STM pills.

2: 27 you can probably sell that PCL82/PCL86 tube (on the right) if it still works.
The funny thing is that, most of them uses 12V/16V heater to turn on & 220V DC anode for both ) tubes, you can just feed it line signal and wire it straight to the Trafo & Speaker since that is technically an integrated amplifier (tube version) on a budget for those era.
If the circuit looks very simple. because it is; that tube (and something similar) are also being used widely on very old TV's.

Seems like a great project for me.
Short backstory: until a few weeks ago I used to listen to MW Radio on my old 1978 GDR (RFT) Radio at nighttime, but the station shut down its MW transmitters. Luckily you can still listen to it via Internet.
So, it might be possible to still listen to this station using this radio, keeping the aesthetic but unfortunately taking away the excitement of listening to a Station 1000s of kms away.

Tel, that LCD ruined the pretty design completely. I also hoped you will reuse hw buttons even if this would need to remove some of the probably clunky mechanics and replace it with microswitches to have nice tactile experience keeping original look. It might be also possible to use some oled(s) to repurpose original display without so brutal change. That lcd looks like if there would a parasite fungus from the future grow there: )

Although I think this is a great DIY project (thanks as always, it is very hard to reproduce for the all day user and pretty expensive part wise. Maybe you should have mentioned that one could also have gone with a simple Raspberry PI + Hifi-Berry AMP 2 + 7 touchscreen together with Volumio OS to have Internet Radio, Bluetooth, Wifi and an Android App to control everything remotely (no soldering or programming required.

GreatScott awsome video as always! another super functional and easy to build Internet radiuo player is Karadio32. I am using ESP32 + PCM5102A +PAM 8403 with a encoder and 1 Oled Display. Karawin has developed some years ago a nice web interface, that makes interaction so much easier. This is 3-4 times cheaper than my Volumio player on RPI+Pirate Radio AMP Hat. And actually ESP32 is still worlwide awailbe, unlike the Raspbery.

Very nice project. I'm trying to do something similar with esp32 for web radio but wanted to output the sound via Bluetooth to a wireless speaker. But I'm struggling with coding and haven't even gotten to the part of using a display and a rotary encoder to scroll and select the different stations. Now I'm willing to give it another go by using chatgpt to help with the coding.

Honestly, after scrapping Bluetooth Volumio on an old raspberry pi (1B or 2B) would have been so much more functionality for around the same cost even if you need an external wifi dongle (because the pi could take over the LCD functionality as well. If bluetooth worked, and you don't want playback with DLNA or from network shares then this might be a better call.

Esp32 is a powerful piece of hardware for its price, but sadly the the part where it falls short is the libraries. Arduino has a such a big backing of the community. I also was working once on the 32 where I wanted ro install the neopixel library on it l, but quickly got to know that there is not a lib for 32. There is a port but it doesn't works properly.
