    Usually when people test amp output , they usually test until the onset of clipping. That amp may not clip for a while.

    Or at all...thanks to PG. ;)

    Probably have to be contented with power readings at 1% THD as there is no PG defeat switch on the MC2255.

    Recently got an MC-2250.
    One channel out.
    Bad LDR.
    Research indicated that is a common problem with the MC-2250 and MC-2255.

    I managed to track replacements down and get mine going.

    It’s something you may want to keep in mind.
    The LDR sits in the input line to the amp so it directly effects the whole amp.
