Soldered up the audio amplifier from the Soldersmoke Direct Conversion Receiver. Built it in my old construction style but next parts will use Manhattan style, which looks even easier. Sadly could not test and just went ahead and built it in hopes that it works because I can’t find my speaker. Ordered another one and will test this week. It has a lot of junk box parts (hence those huge caps and the parallel caps, series resistors). Fun project. Hope it works 😀 #HamRadio #AmateurRadio

Following up… yes, it does work. Still building the rest of the receiver.
@relistan Looks very cool!
I build one a few months back. If you get stuck, please let me know. One tip right off the bat - please make those lead wires of the volume potentiometer short. As a standalone amp, it would work, but when you put together the other three blocks and you feed in microVolts from the antenna and put 100db of gain into this amplifier, every signal gets picked up and you never know which paths the signal takes and it starts howling.
@vu3rdd nicely done on your build. Thanks for the tip. I’ll see how it goes when I have it all connected and keep that in mind if I get howl!
