I managed to get an LA-4a for free.
However, it's missing all switches, all front panel pots (the trim pots on the board are still there), and the Optocoupler.
From looking at this schematic (http://www.waltzingbear.com/Schematics/Urei/LA_4A.htm) it looks as if it should pass signal even without the above connections--Did I miss something? I could definitely use a fresh pair of eyes.
I'm trying to make a minimal amount of connections/component additions, just to get it to pass signal. Currently it is not.
Thanks in advance!!!
