D911 is RJ43 schottky diode and 905,907 are AG01 ulra-fast recovery diodes. They were used on many Denon SMPS products and made by Sanken. You can find datasheets at Sanken. 276xx are the Denon part numbers.

---just not sure how it would only affect your source switch?

I kept refreshing the page several times a day and only just realized there's a page 2! Doh!
Anyway...

When playing a cd it would freeze for a second while the display showed "Ext 1" and the relay would also click and turn off the sound. This would happen several times over the course of a cd. The problem comes and goes every several weeks. A hard power off did not fix it, neither did cleaning the actual physical source switch. I assume it's the diode since the caps are all within 15% spec.

Could you send me the schematic, then I just might go through the entire board and check every single thing a DMM will measure?
