ADC SS-412x Service Manual needed...

Howdy. I'm looking for the service manual for the Sound Shaper 412x by ADC. It seems to have a couple of components that I cannot locate through Mouser, etc. I cannot tell if what I am looking for is a diode or transistor...I've seen both in this configuration, but the numbers correspond to several different types of components including a capacitor. The component is *definately not* a capacitor.

Anyway, sorry for the longwindedness. If I find one outside of here, I'll post it...
