Sadly I realised, that the discrete opamp prototype of the last months are to expensive to manufacture. This is why I designed this discrete opamps, called DOA001. It only uses SMD components. This way the pcbs can be populated by the circuit board's manufacturer. This will keep the cost down. Maybe we can offer these opamps for only 20€. #discreteopamp #doa #groupdiy #gearspace #gearslutz #diyaudio #diyrecordingequipment #diyaudiotools https://www.instagram.com/p/CULI9lRtrHn/?utm_medium=tumblr

Little copper box, housing the DOA325. Shielded and potted discrete opamp. The shielding is fine copper by Würth Electronic, pressed and glued against the ferromagnetic 3D printed enclosure. The copper is connected to the opamp's com pin. #doa #discreteopamp #groupdiy #gearspace #gearslutz #diyaudio #diyrecordingequipment #diyaudiotools #proaudio #proaudiodiy #buschmicrophones #opamp #copper #emi #shielding #3dprinting https://www.instagram.com/p/CT5dQdut0S-/?utm_medium=tumblr

Busch Microphones - DOA 325 Besides the #millmax connection pins, everything is now soldered into place. I can't wait for the @diy.audio.tools.international Discrete OpAmp Tester. This will be awesome! #discreteopamp #doa #lawo325replacement #lawo325 #buschmicrophones #opamp #diyaudio #diyrecordingequipment #diyaudiotools #gearslutz #gearspace #groupdiy #proaudio #electronics #electronicsengineering https://www.instagram.com/p/CTkj2Fytqhn/?utm_medium=tumblr

Look what just arrived! My first discrete operational amplifier and furthermore my first four layer circuit board. The BOM is not finished yet, but its circuit is designed after a famous Lawo DOA. The original was made for a ±11V supply this opamp will take at least ±18V. #discreteopamp #doa #opamp #circuit #schematic #pcb #jlcpcb #electronics #diyaudio #buschmicrophones #diyaudiotools #groupdiy #gearspace #gearslutz https://www.instagram.com/p/CTCpTuoNeoV/?utm_medium=tumblr
