Has anyone who has built their own ICD had problems finding the 1N5817 diode used in the Vpp circuit? I can't find a 1N5817 locally and I'm just a little too impatient to wait for a Digikey shipment. :=3D) I'm thinking of substituting a 1N5819 in place of the 1N5817. The max Vf spec of the 1N5819 (600 mV @ 1A) is a little higher than the 1N5817 (450 mV @ 1A) and I'm not sure if I can get away with this substitution. I don't know how critical this difference might be. Any other substitutions anyone can recommend?
