The circuit does not work as expected e.
Also is it correct that the other lead of the trimmer capacitor is connected to ground according to the diagram? All I get at the output is 0.
I spend a lot of hours checking for connection errors on the stripboard. Thanks for the schematics althought it is mirrored and I need to flip it horizontally to view it.
I am currently using a 47uH resistor-like inductor with a 35pF trimmer capacitor. I finally made it work by: Potentiometer Questions Started by norbss Yesterday at You must log in or register s2c2053 reply here.
It is random no matter how I adjust the trimmer capacitor. This happens on all the TVs that I have. I added pictures of my build front and back on a veroboard.
The FM transmitter audio, however, can be heard clearly with no background noises on my radio. Articles Top Articles 2xc2053 resources.

Hi panic mode, thanks for the detail 2ec2053 on the circuit and the differences with other circuits. I found the layout diagram to be weird and confusing. I replaced the trimmer in the FM transmitter with a variable capacitor from a radio that has a plastic handle so that I can tune it without causing disturbance.
Here’s the datasheet on the 2SC, notice the transition frequency isn’t even listed – pdf1.
Forums New posts Search forums. However, although the audio can be heard on the TV with video after some adjustment, there is always a background white noise.
It seems strange to me. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday 2sc0253 I will work on the main section and post back if any problems. Thus it is prudent to use combined one. Can replace the 2SC transistors with the transistors that I have?

I will continue with the entire circuit when I have time to. The waveform at the output is apparently the input audio waveform, with reduced magnitude.
I got the idea from http: Sure that in 2sc253 begining they appear hardnut, as you progress things would be to your satisfaction. Here’s a page of tips that might be helpful – http: I am currently trying to build the audio section of the circuit see http: I used a 2N instead.
I think I will stick to common transistors 2N and operate at low frequency only. The 2SC has a transition frequency over 1GHz, the 2N is a fraction of that – it just isn’t fast enough.
