Alesis Matica 900

[fixitrightthefirsttime]

Am looking for the schematic for an Alesis Matica 900.

It has a weakened output. Both channels respond the same way with the same level of output/input. Also weak on bridged mono.

Started looking for a common feature, but they appear pretty much separated, even having separate transformers.

Thanks.

Did you contact ALesis and ask for one?

Not yet. I just got started on this amp this afternoon and realized I needed it.

I tore into it and it looks like one of the MJL21194 Q's is trying to fail between the collector and base.

I have not seen the schematic, but it has two seemingly identical trannys but both channels share the same B+ and B-. I suppose they had a reason to do it that way. Seems odd. Maybe one XF is for the + and the other for the - ?
