Blackhawk Amplifiers Valkyrie Drive V3
This one was quite tricky to trace. Got the topology figured out quite quickly but but identifying some of the capacitor values was quite difficult with these Greenies with faded markings. Had to look at several units, all had some minor variations but I think the layout below is pretty much spot on. It is … Read more

The transformer listed is 42TL022 but the more recent version has a different unknown part number which is supposed to work even better. A wild guess would be 42TL002? … Read more
Blackhawk Amplifiers Valhalla Fuzz V1
Here we have a layout for the first (I think!) handwired version of Blackhawks take on a Fuzz Face. But it has a few interesting and useful extra things going on. First, a passive pickup simulator so you can have a buffer upfront or anywhere in the signal chain. Next comes the fuzz circuit itself … Read more
Blackhawk Amplifiers Azoth Baxandall Boost

The Mid control is not actually an active mid band control, it is a passive variable resistor that changes the overall mid slope. Note that this seem to be an earlier version, the … Read more
Blackhawk Amplifiers Morgul Boost
Here is a heavy dirty booster that will melt your Orange, Green or Sunn amp head. And your one knob fuzz will love it.😈. The gain range goes from a fairly clean boost to a hairy and fuzzy overdrive. “Transparent” it is not… It is a fairly simple circuit that boost the whole sound spectrum … Read more
