Lomo 19a9 tube mic manual


Here is a scan of the original Russian manual for the LOMO 19a19 tube microphone.



The full schematics for the 19a9 have been hard to find, particularly the power supply. I’ve saved those schematics as separate files. Click here to see them. I’ve combined the key components for the microphone circuit in the figure below.


There is a discussion about the microphone here at Group DIY.
