Thread: Cst 280, pc2

  1. #1

    Default Cst 280, pc2

    Recently purchased a used CST 280. Very well built machine. The main circuit board has a few bad components. I understand not being able to get a schematic, but would like to know the values of a few resistors on this board. I need the value of R55, R56, R57. The rest of the bad components are redily available. I am sure the resistors are also. Anyone have any information. A look at another board, even a bad board will help.

    Thanks

    Honestly, its much better to replace the boards than to attemp to fix. This is a exceedingly HIGH voltage machine. You get it wrong which is likely (I don't send inverter boards for repair either) and your either dead, or really feeling the hurt.

    All the major components aren't very expensive. I have repaied similar boards in industrial electronics for 20 years. Just thought I'd try a major repair before a new board at $1000 or more.

    As have I in aircraft avionics, and honestly, I wouldn't attempt a repair to this inverter.

    Never the less component specs are not listed anywhere so your on your own
