73P Class-A Mic Preamp

Best of two worlds

I have always wanted to get into the audio engineering side of music, and found the 73 diyRE pre amp to be a great introduction to understanding pre amp topology. On top of this very fun build, I ended up with an amazing sounding pre amp!

Amazing

Let’s just say my wa73 is on reverb. As soon as it sells I’m buying another one for stereo. Wow it makes such a big difference in my tracks.

Delivers Big Time

Not only does the completed kit sound great, it’s built like a tank. Solid construction, great design, superb instructions, great price, and each part of the circuit is clearly explained in the instructions and marked on the PCB so you can understand better what each component does. Very satisfied and will no doubt be buying another soon.
