BC109 Fuzz Face

[pickdropper]

I got a request for a Si Fuzz Face with BC109s in a mini format, so I put together a PCB.  I configured the board so that the input trim and bias trim could be use external pots or internal trim pots.  Obviously in this case I elected to wire up the controls externally.  Frankly, there's so much room on the board that I almost don't know what to do with myself.

The artwork will probably look familiar as it is a modification of the Ge FF art that I use.

Those components are huge and there's holes in the board!!!

Yeah, lots of real estate for bigger parts.

It sure does look bare without the internal trimmers.

Wide open spaces.... unreal...

It's a tough old life

I don't think you can, but don't post a bad build if you ever make one -- several forum members might suffer medical emergencies in shock

Well, I've built so many mini builds at this point, that I sort of know what I'm getting into before I start one.

That said, that doesn't mean that everything goes off perfectly every time.  If you asked most guitar builders (or any woodworker, really) I bet they would tell you that they make mistakes all the time, but they generally don't show up in the final product.  Most minor mistakes can be corrected invisibly.  By far my biggest issue is laser etching gone awry.  But in those cases, it never makes it to a finished build.

Hey, I always use sockets for transistors but for Si transistors soldered directly to the board, is it okay to solder them in or do you use a clip on the lead so the heat does not kill the transistor? I am going to make a bc109c FF really soon...
thanks

I don't think I've ever killed a transistor by soldering it in.  Just get in and our reasonably quickly and you should be totally fine.

It's fine to just solder them in. Just be quick like pick dropper said. I only socket things I want to experiment with.

Great work.  I love the simple graphics and the incredibly clean inside.

I love seeing people work in 1590A's because I tend to stay away from them (as evidenced by this meme):
