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!
