I need to repair my Bruel & Kjaer 2203 SPL meter. Does anyone have the schematic or service documents?

Schematic is on the RadioMuseum site:

PRR,
Thanks for the reply. After a bit of poking around I managed to download it. Now I'll take a look inside. I suspect a bad cap may be pulling done the voltage but who knows. At least now I can troubleshoot.
