Here is a scan of the original Russian manual for the LOMO 19a19 tube microphone.
To download, right click and save etc.
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’s a discussion about the microphone here at prodigy pro.
Here is a Russian language manual for the Lomo 19a9 tube microphone, including schematics for the mic and power supply.
Thanks to Alexander Sonichev for proving this.
