Honestly I had no idea leakage was a thing with diodes. I also didn't think that might be why I like some of the diodes but it totally explains why some are really clear and much less gainy.
Only changes I made on my layout were ditching the charge pump and plugging 18V into it, using studio grade opamps and adding some diode switching. Audio path is 100% klone. Diodes are socketed so I can A/B test with a toggle on top. Here's a link to the build report.
That sounds interesting but the link is just taking me to the start of this thread?
Thanks. I liked the Silver Pony quite a bit, too. I've always felt the Klon filtered off too much of the upper mids for my taste. The leaky diodes help. Another good mod is to drop the value of the 390pF cap in the U1B feedback path to anywhere from 47pF to 270pF to bring back in more of those upper frequencies.
I've got a D&M drive in my build list so I'll socket this cap on that build to check. I've not played with that cap on a klone yet.
At the end, as always, it comes down to taste. However, the cheapest, most commonly available Ge diodes sound great in that circuit and are my personal favorites. Bat41 and Bat46 are good choices, but a bit more aggressive and darker than Ge.
I am pretty sure I have the same Green band versions you mention here, and I believe mine measure "similar", but as Chuck mentioned, of course each tester will measure somewhat different.
