What are the "Balance K" and "Balance E" settings for on the Lomo? I don't get it.
K for Katod, E for Ekran (screen)

OH HAPPY DAY!

Today, a very kind man from the Lomo Museum near St Petersburg sent me the schematics I have been looking for for nearly a year! Many many many thanks to him, if he reads this.

So here it is, the long awaited schematic for the Lomo 600U-17 tube compressor.

If any of you have an idea of how to add a gain reduction meter,  that would be of great help.
But now, I am going to start by recapping it properly (some caps values are different than in the schematics).

It was designed in 1962, my unit is from 1964 if I believe the date stamps on the electrolytics capacitors!

thomasdf, could you post the schematic again please?
Thanks
