Hi,
My article on diode conversions for the OM1 lists a few other sources for Ge
diodes and has a long discussion of the various alternative diodes with lots of
measurements. In fact Ge small signal transistors (C-B or B-E connection) are
generally lower leakage and better suited than the 1N34A's but are often too
large to fit easily. Transistors are often available from surplus stores that
carry transistors as well as NTE.
NTE is probably generally a good place to try as they are available through
hobby electronics stores (and even Consumer stores like Frys Electronics in CA)
and may even do mail order.
Here's the link to my article on Mark's site it lists the nte link and others
too:
