    Rotating pcb holder

    I have the non-Stewmac version of this as well and it works great (and was much cheaper). It's super easy to flip from one side of the board to the other and the small jaws don't obscure much of your PCB footprint. Haven't had any issues with it other than it maxes out ~7-8" width if you're...

    TC1 users, some questions for you

    Mcknib is right, it should test most components without having to do anything funky - One exception is JFETs, where it will tell if you if it's N-Ch or P-Ch and the pinout, but won't give you VGSoff or Idss. You'll need something like a Peak DCA75 or the Greatly Improved JFET Matcher II. If...

    JFET Shootout

    This would be my guess as well, most of the through-hole J201s I've bought have also tested higher than their SMD equivalents. Interestingly, my through-hole 2N5457s tended to test lower than the SMD version. If you want to peak around at a bunch of different JFETs I've tested, I've shared a...

    Only getting 1.2V at 9V jack [with Low Tide Modulator]

    Post pics of the front & back of the board, maybe we can spot something.

    JFET Biasing - part 1

    After first spotting it in the preamp section of the Low Tide, I've been seeing this direct-coupled JFET-buffer setup a lot lately (Beetronics Fat Bee, JC-120 Preamp, JCM800 Emulator). Most of those circuits use it before a tone stack or into a power amp, and the Low Tide uses it to split signal...

    DeadendFX Hooke (Analog Spring Reverb)

    Man, that thing looks great! I love the luxurious red carpet look inside, and the graphics work well against the huge enclosure. I built one of these on vero and it's the best circuit I've made that uses the Accutronics blue reverb tanks. Suuuuuper drippy with the Dwell turned up, and it never...

    Honeysuckle OD - sub for MA150

    If you compare the If vs. Vf plot, 1N4148 is a pretty good substitute. It has a slightly different Vf, but unless capacitance or recovery time is critical to the sound, it should be a perfectly good sub.

    SOLVED Low Tide - LPG not working.

    The envelope part of the LPG does indeed send a control signal to the LM13700. It's actually a control current, but I believe you should see a change in voltage if you probe after R29 (at Pin 1 & Pin 16 of the OTA). Both pins are connected, and the voltage should change as you play harder. I...

    What's on the workbench?

    You could always crowdsource it, people here are crazy knowledgable & are kind of doing it anyways in help threads. Just throw up a PCB pic or schematic with values & part numbers and have people aggregate the info into something usable. Most trimpots are pretty easy to understand, a schematic...

    Those of you who use Dale resistors…

    Used to love this place when I lived in MPLS! Definitely some work to dig through their stock, but they seem to have an endless supply of cool stuff.

    About to embark on the Low Tide Modulator build

    Post away! Like many things on here, it's a true community effort. Probably should include the info in the build doc at some point as the trimpot functions aren't your standard "trim drain to 4.5V" adjustments.

    About to embark on the Low Tide Modulator build

    How do you have the DIP switches set? I've found the Boost setting to be noisy (although not in an unpleasant way), so try turning them both OFF to get a lower noise floor.

    About to embark on the Low Tide Modulator build

    Full disclosure: I compiled/wrote this, mostly because soooo many posts had the same issues that I had when setting up the trimpots. The end result of taking the time to set the trimpots is an AMAZING sounding pedal, which does things I haven't found in other circuits. Keep in mind: The...

    Low Tide Whistling and Noise/Hiss

    It depends on how you prefer to have it set up, but yes. The way my Low Tide Gate trimpot is set, there is little to no signal coming through with LPG at 0%. I prefer this as it gives me everything from signal only peaking through with hard playing when set to 0% all the way to the LPG...

    Low Tide Whistling and Noise/Hiss

    I also had trouble getting the Gate & Bias trimpots set properly and ended up collecting a lot of info on setting them. I've underlined the step below, but you'll want to test the range of your LPG control each time you adjust the Gate trimpot. Unfortunately, both trimpots have quite narrow...

    1054 vs 7660 for higher loads

    I remember running into this CLR issue on a build with that +-15V LT1054 board. I think I settled on 10R or 15R as well.

    1054 vs 7660 for higher loads

    Not sure the exact function, but it looks to be part of the charging circuit for the negative rail charge pump. I took this circuit directly from the LT1054 datasheet: I don't see any dual output voltage doubler designs on the ICL7660 or TC7660 datasheets, so I'm not sure if it's required or...

    1054 vs 7660 for higher loads

    I had a few +-15V charge pump boards made up a while back that used the LT1054 and they've worked great so far. I haven't really pushed them to test out what kind of current they can provide, but here's the schematic:

    Solder won't flow right ...

    I'm always interested to find words that are (mostly) unique to one particular field. Here is another fun one for you: Disproportionation Ever watch the small bubbles in the head of a beer combine into ever larger and larger bubbles? That's disproportionation. The science of beer foam is pretty...
