    Need better info and the pictures of the rest of this box.
    "200v 30 A Rectifier" Where is this info from?
    So far it looks like some kind of power supply.

        These power supplies were butchered by the previous Tech or whoever tried to repair them. There is a voltage divider section that has been moved off the main board entirely. The 339 circuit is giving me fits on what it wants to see Voltage wise before it will enable.

          "Rectifier" in this context may be telecom-lingo for power supply. Based on the large number of Wima, Roederstein, and, possibly, Siemens film capacitors, I'd guess it's a European product, possibly Russian.

          You may have to stare at the thing and hand-draw a schematic.

            I believe the unit is German. Here are some better pics. I managed to get a few of them to run . On the others I'm having a hard time getting the opto to fire.

            Thanks in advance for any advice .

              I do believe Gramm Analagentechnik GmbH is a German company
              I entered "galvamaks" into google translate and it detected the language as Latvian and the translation was "headache" seems fitting
