diodes

[Jim Roik]

Thanks Murray.

That is what Heath used for its balanced modulators, at least in my SB-401.
The current reference I have is that the 1N191 is replaced with a
1N4148.for new design. Some day I'm going to remember how to read the diode
code. I gather the bands are the last digits and the blue band indicated
the cathode?
