  I have also made one transistor Fm transmitter circuit using BD135 ,it sounds really great with good range of 200metres ( using just wire antenna) , it is basically Brazilian design, i got it from Newton c braga website.

  Even just "engaged" without "wide" or "theoretical" you might prefer it. It's a great fun thing. I have one, its a long term project, I have an upgrade kit coming which I think is just new caps, and I'll get the RCA's changed for something better (bolt through surface mounted) as modern interconnects are a bit too wide for the holes in the chassis. Great video, thanks for taking the time and the research. I feel lucky to have picked one of these up in the UK in great condition.

  Quick question: What level of sensitivity should I expect for an All American Five radio? For a GE model 400 radio that I am restoring, the signal at the antenna needs to be above about -40 dBm (3 mV RMS into 50 Ohms) in order to hear the station clearly. This seems high.

• 
  @AllAmericanFiveRadio16 күн бұрын

  So I guess your volume and sensitivity are low. Have you tested all the tubes? I’ll be glad to help in troubleshooting your radio. I would need te voltage at each plate of each Tube.

  Can you explain how you’re biasing the 2N2222A transistor? What confuses me is how you determined the 33K resistor value and the -7.4VDC that it connects to (yes you said you measured the -7.4V, but that’s after you built the circuit.). To put a finer point on my question, why bias the 2N2222A with that resistor topology rather than the traditionally shown voltage dividers/diode biasing we see with class-B amplifiers in numerous online examples?

  @@AllAmericanFiveRadio Thanks for the links (and I did watch them) but they do not answer my question. Maybe I didn’t ask the question clearly? So, some background: (1) I know how to bias a transistor’s base for an amplifier using a resistive voltage divider and also how to calculate the values of the resistor divider before building the circuit; and (2) you are not using that traditional topology for base biasing, instead you are tying the top of the resistor divider (33K and 9.4k=4.7K+4.7K) to the _OUTPUT_ of the push-pull pair before the DC blocking capacitor. My reframed quesiton: The output of the push-pull pair changes with the input signal to the 2N2222A as a consequence of the gain of circuit, i.e. the the DC offset being added to the input signal, at the base of the 2N2222A, will change with push-pull pair output, causing that delta to also be multiplied by the amplifier’s gain. This would, I think, cause nonlinearity in the amplifier and distort the signal, increasing THD. Was it just trial an error on how you selected the 33K and 4.7K resistors? Or did you actually compute the values? If it is the later, could explain your process for doing so?
