Another great and entertaining video Mr Shango sir. I don't know if anyone else has ever noticed but unlike every other channel Shango never begs for likes or does he ever ask anyone to subscribe to his channel. Shango is a blessing to all electronic hobbiest!
That audio stage is a complementary symmetry amplifier, the transistors connected as diodes in series are used to establish a bias voltage between the bases of the output amplifier to eliminate cross over distortion. It acts as a push pull amplifier, but is actually a totem pole series circuit, with the upper and lower transistors driving on alternate half cycles of the signal.
I read in some old popular mechanics books (do it yourself) that multiple transistors was a gimmick. It said, the more transistors it has doesn't make it better. Quality transistors do.
I've seen radios of the period with transistors soldered into the board but not connected to anything. It was a way of using quality control failed parts to get the transistor count up, con the consumer into thinking they were buying a better product, and keep the marketing department happy. In this case, it seems to me that they've found a bunch of failed transistors that they can use as diodes rather than scrapping them, saving money and increasing the marketing bullsh*t factor into the bargain!
The problem of these faked transistor count radios was big enough for congress or the FTC to pass a law about it in the sixties - I have an article about it in an old Consumer Reports somewhere I'll copy when I run across it someday.
Nice to see another transistor radio video! I actually just did my first transistor radio that I got from a thrift store. A $5 GE from the late 50s with 5 transistors and a diode. Wasn’t working initially but after cleaning the battery contacts and letting the electrolytics reform it’s working well now!
Here we go again with the spam replies. Im actually on t me but I don't solicit anyone to hit me up
"solder wick is expensive, exceeds value of radio"
"nycroin dropelopelfloschur" has to be one of the best responses yet, with 'popcorn' playing in the background.
Shango dancing to popcorn while messing with phone scammers is something I didn't know I needed

I can't believe they got these working with only 12 transistors. Cutting edge circuit design!!!
Thanks! Shango for all you do. This isn't much but it's something. Maybe you could buy a nice shiny new transistor made in China.
I would never have guessed this piece would receive so well. Great job, Shango.

That's a seven-transistor radio, they just used 5 transistors to bias the power amp 😄
Hot mushrooms and plinkotwerkulation. It's a good day.
Another meaning of "noble" is "unreactive", meaning it does nothing of any account.
Funding the madness. Nice thorough repair video. Still better than cable TV
"Quality Control Approval" 🤣

Directive issued from the company CEO "get that transistor count up, we have millions of factory rejects we need to use up"
An hour of transistor radio repair is a welcome sight! - the content is always appreciated, keep up the good work.
