Dear folks,

Did somebody tried to improve the noise floor of the LM386 by adding the 10k resistor and 10n capacitor in series between pin 8 and the output pin as it was published in the Oklahoma QRP News Letter and then after by KA4UOS in Sprat nr.79 please?

I am interested in the results...

Thank You for responses in advance.
