Any smart folks out there had success building the DBA Armageddon? I've been working on the Moonn Electronics Asteroid, which from the description is based upon the Armageddon (http://dirtboxlayouts.blogspot.com/2019/07/death-by-audio-armageddon.html) but still scratching my head on this one.
I've put together the v2 PCB with the recommended components from the build doc (https://www.dropbox.com/s/dyyin1ma8q527ug/Asteroid Doc.pdf?dl=0), but still only getting a very faint fuzz sound when both the loud and fuzz pots are dimed. Checked and double checked the offboard wiring as well as all other components, and it looks to be correct. Checked for any unintentional bridges and cleaned up flux from the board... nothing that i can see. But from my limited experience with fuzz circuits, this usually indicates something is up with the transistors. Then again, I'm still learning the basics so definitely could be wrong.
From what I've read about the 7 transistor Fuzz War/Armageddon circuit (I believe this is the basis of the Asteroid), the transistors can be a bit fiddly. I've gathered seven 2n5088's with hfe of 350 (within 1 or 2 hfe), and tried a few similar subs (2n5089, 2n3094) but no luck. I'm guessing there may be another issue, but hard to tell since it seems to be a somewhat uncommon build and not a whole lot of info out there.
The v1 Fuzz War threads here have been super helpful thus far. But not sure if the addition of the filters would deviate much from the Bellum MK1 concept. Any ideas on where I should go from here? Thanks!!
