The Earthquaker Devices Bows is a straight-up germanium Rangemaster with some modern tweaks. It uses an NPN transistor and has a switch to swap to a larger input capacitor for a full-range boost.
The space above the transistor on this layout allows it to be mounted on its side (bent over 90 degrees), as OC transistors are pretty tall, and if you use the mounting points, you will need to reduce the height of the transistor in the enclosure. It's generally a good idea to place insulation on the legs of the transistor so they don't short when you bend them. If not all the legs, at least the base leg in the centre of the three.
thanks for all your hard work, keep well and happy new year
