Just ordered a couple to check out. I had an idea for a DIY project but didn't want people to have to build a flyback supply to handle the current required for the project. These may be a good fit.

It's going to depend on the actual flyback controller IC being used, but the answer is usually not. EDIT: Based on the datasheet it looks like they're using LT1619 as the controller, which does have a synchronization option to run multiples in parallel with an external clock, but the modules...

Tayda is where most people get them done, that's what the templates were designed for. https://c2celectronics.com/drill-templates-and-artwork-files/

Yup that's basically how I'm treating it for now. There's only one other mounting point on the board (added because I had room), the mounting screws for the transformers are going straight into beefy standoffs into the steel chassis as the main mounting point for the PCB. But I say "for now"...

That's absolutely the case for a power transformer and output transformer, but both of these are output transformers and this amp does not have a power transformer.

Close, tube headphone amp with built-in IR loader. Black and white alien spaceship looking dudes on the left there are transformers for the flyback power supplies. The giant transformers are left and right output transformers. Not sure why the 3D model doesn't show up for my USB port, but...

Every transformer is a board-mounted transformer if your board is big enough.

You missed the part in the build instructions where you need to install the jumper for true bypass operation. Jumper these pads on your board.

Single FET boosts always invert, single FET buffers never invert. If you need a non-inverting boost or an inverting buffer, you need an opamp.

I appreciate the hell out of the information and the amount of work that went into this, but wow my eyes do not like looking at it. Quick suggestion from a non-software person: add a "deselect all" button so users can start from blank and add things one or two at a time.

I rolled tubes in my SVT-CL when I first got it, I don't remember what I ended up with, I'll have to open it up and see what ended up in there. It is worth mentioning though that my cab (Eden 610) is a bit brighter than the Ampeg 810 fridge, so that makes an impact as well.

This is exactly what the world needs right now ❤️

Sometimes the loudest rats are those that make no sound at all. RIP Rat Hole.

Like a footswitch-shaped expression pedal? Is that kind of what you're picturing?

I was really bad at it to the point that my wife let me buy a CNC machine so I would stop spilling ferric chloride on the floor :P

I've never heard anyone actually say "EN-EFF" out loud for nF. At my day job we use abbreviations like "mike" for microfarads and "puff" for picofarads. Interestingly neither of my day jobs since university have recognized nanofarads as a thing. Anything up to about 10nF is thousands of...

When I first started building, Tonepad and Madbean were pretty much the only options for PCBs. And if you didn't have the money to buy actual PCBs, you used the Tonepad layouts to etch your own with the ferric chloride that you could buy down the street at Radioshack (this was 2014). I think...

Sometimes you just need to sit down and design jumbled garbage.
