    Assuming DOUT and Din (red traces on right side) are at 10ghz, Will emi interfere with electrode inputs on the left?

    Man at page 3 you aren't even into the Scarlett Johansson pics. Looks like I didn't start commenting until around page 56, but yeah I remember reading the whole thing as it was happening. What a time to be alive.

    Assuming DOUT and Din (red traces on right side) are at 10ghz, Will emi interfere with electrode inputs on the left?

    You'll have to excuse the responses, but this is a forum dedicated to effect pedals for guitar and bass, so we're musicians, not general PCB experts. That being said a few of us actually are EE's and like looking at all types of PCBs. If you're wondering about EMI effects though we'll need to...

    Steddi, Go! - simple tube D.I.

    Sorry I missed this one, but Mick is correct. No benefit to a higher voltage for C1 unless you already have it on hand and it fits on the board. You'll be seeing low voltages there on the cathode, so 100V is more than enough. Absolutely no benefit to 0.5% tolerance resistors in this build...

    Steddi, Go! - simple tube D.I.

    100V box film caps are fine. C1 is on there, 6th from the left in the main row of components. https://www.taydaelectronics.com/0-68uf-100v-5-polyester-film-box-type-capacitor-size-small.html

    Effecth?? what kind of DSP chips

    ADSP is another product line from Analog Devices, which would make me guess it uses the same SHARC architecture as the ADAU series. If you can't figure out how to write an algorithm for FV-1, you're not going to like the development process for SHARC.

    Effecth?? what kind of DSP chips

    I've done a couple designs with ADAU1701, and there are a couple things that make me think that's not it. The ADAU1701 datasheet calls out a 12.288MHz clock for 48kHz sampling, and that board calls out a 24MHz clock. Also ADAU1701 typically uses a BJT as part of its internal regulator to...

    Yup, the whole thing is obviously backwards.

    How do you typically Clean flux from PCB

    Everyone in my house has an electric toothbrush, so I just use whatever brush the dentist gives my kids, so I get a new one every 6 months.

    Back In Stock Updates

    Unagi E4305 transformers are out of stock on the website right now, so you won't be able to get them by themselves or with Nobelium or Steddi Go PCB sets. I placed a restock order in August, they're expected to ship towards the end of October.

    Bassdude V1 cathode resistor question

    Bassdude is based on the 5D6 Bassman, which does indeed have a shared cathode connection across two triodes, but since each triode acts as an input stage for the respective channel you're only using one at a time, which made me think the 820Ω cathode resistor for V1A was fine for Bassdude...

    circuit modifications in amps

    There have already been a large number of resources suggested in this thread. Start with those. Also, as stated before, if you want to share what your general goal in modification is we can certainly point you in a more specific direction.

    circuit modifications in amps

    A quick summary: 1) Don't rush. You seem to be in a hurry to get in there and start poking around, and I think that is what is scaring people. "Tube amps can kill you" is not hyperbole. You can actually feasibly die. We're not trying to gatekeep, obviously you can't learn how to work on amps...

    circuit modifications in amps

    If you're trying to remove resistors and capacitors at random, you're going to run into some problems. There are of course rules to follow. Some weirdo made a post a while ago with an introduction to tube preamp design, that may have some useful information for you. But perhaps if you could let...

    Whammy pitch Octaver fv-1 (SpinCad)

    If you're set on using SpinCAD so you can listen to patches without FV-1 hardware but aren't trying to learn how to use SpinCAD to write patches yourself, you're going to have a hard time.
