    Spritzer probably does, though the Mjolnir Audio DIY page doesn’t seem to list them any more. You might want to ask him. I found his XLR input and Stax jack PCBs quite useful also.

    I'm not sure how much voltage that part of the circuit sees. In any case, I had better luck ordering a bunch of extra RN60D resistors and hand-matching them to <0.1% than relying on the manufacturers' matching process. YMMV, of course.

    That transformer looks like overkill to me. Maybe it's for a GRHV cranked to 450V? I think most people build at 400V. I ordered mine from Toroidy, with the following specs: Primary windings: 2x 115V (60cm leads) Secondary windings: 2x 335 VAC at 200mA (60cm leads) 16-0-16 VCT at 500mA (60cm leads) Works well. You should review the BOM carefully and check it against the boards to make sure you know what you're buying. You may need to replace some outdated components, but this is easy, and will help you make sure you understand exactly what you need. As for Stax sockets, I think most of us buy them from HeadAmp. You can use the eBay store: one, two, or five pieces. Happy building!

    What are you reading now?

    Things have changed since we last discussed The Cursed Child. I saw it in New York last week... and, let's just say I almost immediately ordered tickets to see it again in San Francisco this fall. PS: I think the two-a-day format with a matinee show, dinner break, and evening show makes for a fabulous day.

    The Multi Amp aka Dynalo Mk2

    Don't know about Mini compatibility (I'm still working on mine), but I built two full-size Dynalos with MPSW parts (I have a small stockpile). They run entirely cool as far as I can tell. I never checked with a thermometer, but there's no sensation of ambient heat if I hold my hand near the boards. Honestly seems like a good idea to use the cooler parts if you can get away with it, though it seems to me like it'll be a tight fit to stuff all those TO92 packages in such a small space.

    I'm still a huge fan of the Lone Wolf series by Joe Dever. If you grew up on that, check out https://www.projectaon.org/en/Main/Home for a really fun nostalgia trip.

    A Game of Thrones Pilot Greenlit

    My views on S7 and S8 fit neither the apologist nor the hater narratives, so I generally try to stay out of GoT discussions. That said, I think this Twitter multi-post does a pretty good job of explaining the pacing changes in the concluding seasons: https://mobile.twitter.com/DSilvermint/status/1125856091261136896

    @tyrion: What strap is that?

    The Multi Amp aka Dynalo Mk2

    Is the AOT resistor supposed to form a voltage divider with the 10k it's next to? Trying to figure out reasonable values for that resistor to order.

    The Multi Amp aka Dynalo Mk2

    On the mini Dynalo, I never understood the pieces labeled "AOT". They're marked optional in the BOM, and no one seems to have soldered them. What do they do in the circuit? From the photos posted, most people populated the 10k resistors next to AOT. They aren't in the Mouser shopping list, but are they needed? I plan to use the on-board regulator (soldered with paste and hot air) if that makes a difference.

    Thanks @MartinC700, but I just picked up 100 pieces from Digi-Key. As @shaihulud pointed out, it's finally back in stock. 😀

    Neither, sadly , but I’ve been into HP for a long time and read the published stageplay script when it first came out.

    @TMoney: Try to finish the series and take a few weeks off from Harry Potter before seeing (or reading) Cursed Child. It's... different. In a good way IMO, but it's still good to let the main story settle in your mind before you jump into it.

    I posted a question about this on the advice thread two years ago, and here’s a helpful reply:
