I don't know man, those are FOUR CENTS a piece! I mean, a set of 25 will cost a whole EIGHTY CENTS! That's half a chocolate bar, I have to save up for that, I have my priorities you know. Besides, they only have 9,346 of the things, by the time I scrape enough change out from under the floormats in my car, they'll be out of them already... :mrgreen:
Ok, seriously, I wonder if it is enough to make a difference? Some differences in specs are not really a factor, but the 0.2V difference in voltage drop is significant, as well as the 2pf difference in capacitance, especially since one is double the other. However, reverse recovery time is the same.
Looking at the VCO, and without doing a lot of complex calculations (Kind of in a lazy mood right now), it appears that with D30 and D31 any differences would be irrelevant, and with D25 being located in a current source, I'm not sure how much, if any, the effect of the voltage drop and capacitance would be.
Unless you count D24, there are no diodes in the filter, D24 would affect accent more than anything else. Given its location, I wonder if the difference in voltage drop would be noticeable. It may be, perhaps you or bcbox could take a look and help figure out if it's work testing.
D24 of course brings us to the VCA and the EG. If there is a difference, I think it would show up the most here, mostly because of the difference in voltage drop. Can you or someone else help make a determination on whether or not this would be worthy of testing? I just may be. I don't know if the 0.2V difference is something antto can model in his software synth or not, but it may be interesting if he can.
If enough people chime in thinking it may make a noticeable difference, I'll at least go ahead and unsolder and socket D24 and all the diodes in the VCA and EG. By the time I finish some more of these other tests, perhaps I will have scraped enough loose change out of the car to order the 1SS133 diodes :mrgreen:
