I have a question related to the audio signal of the K2. I have completed the base K2 and during stage 2 I was already concerned about the low audio output.
I first thought that my headphone was to blame, a 16 ohm unit that is not able to transfer all the audio power from the amplifier but now after completing stage 3 with the speaker installed I have a very meagre audio output. I'm not talking about loudness, I 'm talking about a low level audio signal of only a few millvolts at the standard 4 ohm speaker. This with AF and RFC fully clockwise. Further I disabled AGC and then it gets a little bit louder but if I use the speaker I can hardly hear, I have to use the headphone to hear . Is there any easy way to check the audio amplifier, I'm thinking to put a 1khz tone at the input of the LM386. Thanks for suggestions.
