Alright, here you go my dude.

Primary impedance is 2.0MΩ, secondary is 1.4kΩ (measured at 8kHz). I measured the frequency response when I got them and I remember it was flat on the low end down to 10Hz (I wanted them primarily for bass), I'll have to dig up my test results to remember where they started to drop on the high...

This is a new PCB design, it was designed for 125B and obviously has a tube. I'm still calling it Gondwana, this is just the prototype of what I wanted Gondwana to be. I have another project I've given the name prototype as a working title and it's just been confusing, because I have a prototype...

Still just a prototype, but a very functional prototype.

I have a draft datasheet I've been telling @Passinwind I would finish up and publish for a couple years now, I should really do that one of these days. Anything in particular you're looking for as far as specs?

Man if I had a dollar for every time I've said that, I would have many many dollars. Looks great though my dude, all things considered I would call this a win.

Yeah it took some effort but Unagi were custom wound to my spec by a Chinese company. So I designed them, but I don't build them. Part of their team (it's a large company) are actually traveling to Chicago next week, we're going to hang out. So cost was a big factor, but also getting exactly...

I obviously profit when people buy Unagi, but I have no issue recommending the Lightning Boy MC15, Mike (the owner/builder) does excellent work and is great to deal with.

It would be a theoretical nonzero impact on the LDR, but I think depending on how far it is from the LDR, and especially if it's on the opposite side of the board like it usually is, the impact would be very close to zero.

That's one of the main reasons I started buying the Unagi transformers, everyone else worth having was either difficult to deal with, prohibitively expensive, or both. I was able to get a couple Jensens when I first started doing D.I. builds, but it quickly started feeling like they didn't think...

The Rev version uses NOS tubes, not sure the brand. Neptunium and the C2C Nobelium both use JJ. The XLR signal path of Nobelium only uses one tube, so if you're just using the XLR then the Neptunium and C2C Nobelium will be identical. Same circuit, even the exact same components. The Rev build...

NOS tubes, Dale resistors, Wima caps, Jensen transformer. The $800+ pricetag makes sense :P ...still uses my PCB though 😁

Excellent, that's always what I want for people. Debugging skills are important because eventually something will go wrong, but part of "design for manufacturability" means making it as easy as possible for the builder to succeed, and that's always one of my goals. A person with an engineering...

I've been 3D printing my sockets for years. Injection molded sockets last longer, but they still don't last forever and the cost of replacement adds up when you're using them a lot. It's especially annoying because there are some values that get used more than others. A "full set" of sockets for...

It was brought to my attention that the Wrecking Ball parts list has a mistake as well, it only calls for one 2x5 right-angle header instead of three. That has now been fixed.
