    SOLVED Twin Face - Si/NPN side, odd Q2 voltage?

    So I used my DMM and checked all the resistor values, the trim pot value, and continuity everywhere I could think of. All the sockets have continuity to the other side of the board as well. Here's some photos of the NPN side. I did hit it with contact cleaner right after this too, just because...

    Your First Transistor Spice Rack (Input needed)

    Yeah, I didn't bother with a full list of Germanium transistors, because (a) you're likely to find them in small quantities only, (b) there seems to be a lot of variability within the same model of transistor, and (c) people seem to enjoy trying whatever they can in different circuits. I did...

    Your First Transistor Spice Rack (Input needed)

    While I've been around for a few months, I am constantly surprised about all the transistors that seem to pop up in schematics that I just don't have. A majority of the time this is to be expected, such as when I look up to see what an OC71 is, and what prices they command due to rarity. But...

    MODIFICATION Common Mods For Many Circuits

    so if I get this correct, the pot lugs are 1: GND, 2: to the transistor's somethingorother (I'm gonna guess the base), 3: input signal (?)

    SOLVED Twin Face - Si/NPN side, odd Q2 voltage?

    Bump, because once this weekend is over I'm hoping to disassemble the enclosure and check the other side of the pcb. It looked OK last time but maybe I missed something.

    Anatomy of a breadboard

    Newbie tip: make sure you take care when sticking your breadboard to a platform. Say, the Micro protoboard. I didn't get it square enough, and a "correction" resulted in the entire adhesive layer getting ruined. Fortunately I don't think I destroyed the spring clips themselves, so I think I will...

    Breadboard Emulators

    I saw Brian Wampler's video on how to breadboard, and I think the comments mentioned circuits.io as what he was using. But it looks like that's a subscription service now. With the parts arriving for my Mini Protoboards today, I would like some way to plan something out and maximize my real...

    Loafing Lounge

    That's exactly what I was thinking of @BuddytheReow. I had purchased these green clamp things (shut up, I was a mechanical engineer not electrical) in preparation for a Protoboard. I guess I can use them up and order more. Definitely a good part to have on hand, just like pin headers.

    Loafing Lounge

    This was from a while ago. Clark Gainster. I really need to start developing a neatness strategy, and making a breakout board to handle the potentiometers. Apparently this direct-to-breadboard idea isn't smart. I also ordered some proper jumper wires since then.

    Sandspur

    Of course, fuzz was maxed out. Volume was maybe 2 or 3 o'clock. Maybe I'll breadboard your version once my Microboard parts come in.

    SOLVED Twin Face - Si/NPN side, odd Q2 voltage?

    OK @Coda I finally got a chance to plug a telecaster into it. The fuzz sounds pretty quiet compared to the germanium side, and it's very gated. It loses so much attack that it almost sounds like a fade/in reverse effect.

    Sandspur

    I built two of these - one with BC108 and one with BC109. I can hardly tell a difference. Haven't thought of mixing and matching transistors in the same circuit though. But if I put either in front of a little bit of clean boost, I'm playing straight out of Dark Side of the Moon.

    Da, Comrade, The Soviet Horse Muscle! (Ungula)

    Thanks! I had built a War Scythe previously using the recommended 2N1308 transistors. It sounded good. I wasn't interested in the cleft modifications since I didn't like the sound of the Cloven Hoof demos I had seen online.

    SOLVED Twin Face - Si/NPN side, odd Q2 voltage?

    No idea. I'll have to try that part later.

    SOLVED Twin Face - Si/NPN side, odd Q2 voltage?

    I never thought it would come to this. Posting on the Troubleshooting forum for a Fuzz Face of all things. I guess that's the price you pay when your EE professor never figured out how to explain transistors clearly. Tried to set trimmers before plugging in this Twin Face for an audio test. Q2...

    Happy accident that I found that angle. Bob Ross would be proud.
