D11 looks like an ancient Telefunken general purpose 2A diode. In doubt you have to desolder them. There should be some form of imprint on it.

D10 looks like a small signal diode (like 1n4148, 1n914 , etc), D11 looks like a rectifier diode (like 1n4001,1n400x).
Of course that's just what they look like, their actual PN should be written on them. And any number of different diodes could be in those common packages.

..and I've seen Zeners in exact same packages...

Thanks, guys. Not exactly the answer I was looking for but kind of what I expected. These things are completely unmarked so I was sort of hoping for an a-ha! from someone who may have seen exactly the same before.
I suspect that the lower one is a germanium affair just based upon the application and I found a similar looking package to the white one from Vishay. On to experimenting and listening!
