Check the DC ofset voltages may be one of the mirror amps or a resistor in the preamp if the drivers and other componets test ok in the output section.

Date: Tue, 31 Aug 2004 16:18:27 -0500 I have a well worn CA-870 manual but don't have a CA-870A manual. The last time I pulled one of these old Fisher manuals to help someone it turned out we were looking at two different Fisher units with the same model number. Any chance you can name some of the IC's so I'll know if this is the same before going any further with it? ******************************************************************************************************************* Since 1972 Jim Myers Telrad Electronics Fort Wayne, Indiana Dave Huston wrote: > Would any of you have the schematic on this model?
