    Mmkay, I can't get the drill template updated until I get home, but the rest of the build doc is uploaded.

    Mirage Tremolo - Tube Tremolo Project

    Matchless has always been one of my favorite brands out there, so I guess it was only a matter of time before I got to this one. The Matchless Vibrobox is an all-tube tremolo/clean preamp with a vaguely Vox-ish flavor. Mirage Tremolo takes the Matchless circuit into a 1590BB enclosure, getting...

    I'm almost done with the build doc for Mirage Tremolo, I'll get a new thread started for it when the doc is finished.

    Nobelium - tube bass preamp project

    You may have to do some creative lead bending as that's a 7.5mm pin spacing compared to a 5mm footprint on the PCB. But if you can make it fit then it should work.

    Fryette Powerstation Schematic

    Depends on what you mean by transparent. With a load box you're typically more concerned with feel than with sound. You can use a single 8ohm 100W resistor and call it a dummy load, but it will feel stiff and uninspiring. Most higher-end boxes (including the powerstation) use a reactive load...

    Fryette Powerstation Schematic

    Yup, it's common to have a fan on large attenuators and dummy loads. The powerstation uses a bank of 50W resistors for that, and they're already mounted to the chassis for conduction, but they're single-digit ohm resistors straight to ground so they're taking all the power of whatever amp you're...

    Fryette Powerstation Schematic

    I was talking to my friend that I bounce all my ideas off of and he reminded me that the general consensus is that the power section of the Fryette D60 is the same as the main part of the Powerstation. This schematic doesn't have the reactive load (some good reading on those here) and is missing...

    Fryette Powerstation Schematic

    I thought I had seen a schematic for one of these around as I was considering designing something similar, but now I'm having trouble finding it. If you're looking to build your own then you will of course need a full schematic, and there's no reliable way to get that from pictures. If I were...

    Getting a PCB made from a gerber

    And a bargain at €325 €99. And if you want to change (fix) anything you need to either have Eagle or have a program that can import Eagle files.

    Nobelium - tube bass preamp project

    I updated the BOM a while ago with links to suggested components, but if there is no voltage specified for caps I typically say 50V for film caps, 16V for electrolytics.

    I FORGOT. Sorry. I allow myself to do too many things at once and get overwhelmed. I'll get it on the wesbsite shortly and get the BOM up Sunday. EDIT: Done. https://c2celectronics.com/product/mirage-pcb-set/

    Mmkay, I'll get a very preliminary build doc (pretty much just a BOM) put together today and get them up on the site tonight. I'm calling it "Mirage Tremolo". I know TremoBox doesn't sound as good as VibroBox, but it is in fact a tremolo (amplitude modulation) and not a vibrato (pitch modulation).

    I won't be providing parts or instructions to make your builds look like this, but this is what it's based on.

    Oh right. I finalized a new layout and ordered 50 PCBs to have in stock, then got distracted and never released them lol. Should we wait for me to put together a build doc, or do we want my typical style of "build the airplane in the air"? It's a 1590BB build, nothing super weird, same general...

    Possibly stupid but easy tube project based on the Electra circuit.

    A typical approach would be to use the first stage to push the second stage into a natural overdrive. I will continue to give the disclaimer that I'm not an expert, but I've learned a bit over the years, and I made a post a while back that covers some basics...
