Hi,

I have a number of glass diodes matching that description,
the bulk of them 1N4149s. They're described in my data book
as "silicon planar, high-speed switching". A 1N4007 would
probably do as a substitute.

The future was never like this!
If it's a little black cylinder with a
white/grey
band at one end, about
6mm long and 2.5mm in diameter, it might be a
1N4003. That's a very
common rectifier diode in Europe. The last digit
encodes the PIV, for
most applications a 1N4007 (the most common one) is
fine.
It's actually a little blue cylinder (made of glass),
that has a black band on one end. Should have
mentioned that before - it looks kinda like a
germanium diode, but in the schematic they seem to
have it doing rectifier duty. I've got tons of
1N400x's, so I suppose I could try that, it looks like
it should work, given the circuit. Did they make glass
rectifiers at one point? (non tube, rectifiers, that
is...)
