  • Hollinger PA - no sound

    fx loop send works, no speaker out sound. I see some carbon burn marks on one of these output chips. There are 2 11-pin output devices in this and they are not labeled in any way. What part # might these be? I figure I'll check the surrounding components and power supplies etc and replace the outputs and should be fine.

    Ok this power amp IC looks alot like this one on page 4 of the link below - labeled DBS.P. However the one in this PA is an 11-pin. Any ideas anyone?

      I thought I responded last night, but I guess not. Look up the data sheet for the common LM3886. it has 11 legs. DO the connections make sense for your amp?
