This one has the same holdup as Space Heater, it's going to go into a 125B enclosure but the current Tayda 125B have thicker walls than the Hammond enclosure I designed around so I need to source some enclosures (out for delivery today) from somewhere else to make sure I can make it fit without asking people to grind down the lip on the bottom cover.
ANYWAY to the point, Echo Foxtrot is a simple tube preamp using an EF86 small-signal pentode, famously found in the likes of Vox and Matchless amplifiers. EF86 has a very distinct tone that is hard to get from another tube, there's just nothing quite like it. It's a single stage, so it won't overdrive by itself, but naturally it could be pushed into overdrive by a boost in front, or you could use it as a boost to push something else into overdrive. Super simple controls, just Volume and Tone. Takes a 9VDC input and steps it up internally to 240V or so.
I've designed a through-hole DIY board for this project, but SMD is so much faster to verify for prototypes, so I put that together last night to see how it sounds, and it sounds excellent. I'm going to try to get the DIY version verified in the next day or two so I can make those boards available, but this is what the SMD version looks like:
