    Hello.

    I have a Spectral DMA-180. One channel has a large output offset and it's very unstable, along with a loud humming sound. After re-soldering the working channel, I discovered that the culprit was a transistor in a metal housing marked SIVN 0535N2 9212.

    I found your thread
    Spectral DMA180 - multiple issues where you asked about the transistor type, but you didn't get a response.
    These transistors are the same in both channels, unlike your amplifier.

    Were you able to determine the type of these transistors? I clearly need a replacement, but I don't even know what it is. The component doesn't ring like a bipolar transistor; it might be a field-effect transistor.
