Diode Questions
I am working on a small electronics project that needs a few 2N388
geranium diodes. The only problem is that they are hard to find and expensive. I figured I would give another NPN diode a try but I'm not really sure what to look for. Can I just look for a close match based on one or two specs? Is this something where any diode will do as long as it's rated to handled the voltage, current, etc? As you can tell, I don't know a whole about this (I pretty much just know some basic electrical stuff and what some electronic components do) but I would appreciate any help someone could offer. -Brandon R. |

Diode Questions
My mistake - "GerManium," with an "m." Sorry for the typo. Anyway...
The schematic can be seen at http://fuzzcentral.tripod.com/bender...rschematic.gif I have everything I need except for the diodes, which I gave the specific part number for in my original post. They were originally manufactured by GE in the 1950's but are hard to come by so I am hoping to find a close match that I can substitute. Specs can be found at the two addresses below. The first one, from the military, is pretty thorough. http://www.dscc.dla.mil/Downloads/Mi...l19500ss65.pdf http://www.semiconductorliquidate.co...ch?ss_pn=2N388 |

Diode Questions
Ugh. My mistake again. :-) I've been fooling around with this parts
list too long. Actually, I looked around online a bit and found a few sites with information on which transistors make good replacements for this type of project. |

Diode Questions
The forward drop across a silocon diode is ~.7V and only 0.3V for germanium
so if the diode is acting as a reference or the circuit is depending on a certain drop you should not substititute a silicon diode, as a rectifier you can probably sub without problems, half of a transistor can also be used as a diode so you could sub in a trans...
