For power supply rectifiers I stock 2 types that can handle everything....1N4007 (1A, 1KV PIV) and a 1N51?? that's rated for 3A 1KV PIV....The higher current part is pretty much never necessary, but anything over .75A I try to use it for so I'm not running the 1A part too close to it's rating.
In convergence and detector diode applications switching time, junction drop, and capacitance become more important.
Boost and focus/HV applications are pretty much the same as B+ rects but with faster switching time requirements.

Thanks! I will probably just replace it with a 1N4007 then if that will safely work as I have a whole bunch of those in my parts box.
