Let's see, best as I can remember it the breakdown of costs was (approximately) the following: Circuit Board: $20 (eBay) Electrical components: $50 (Mouser) Front & back panels: $100 (Front Panel Express) A bit ironic that the panel machining was more than the cost of the actual power...

I offered an extra AD797 phono stage with a Pete Millett linear PSU to @Audionut (as I built three of them for some reason I can't quite fathom). :)

Second jab is tomorrow afternoon. We'll see if it knocks me on my ass or not.

One other idea (that I know I've mentioned elsewhere) is that you could also sign up for a HackBoard2 computer preorder for $115 (shipping April 30th) and buy a 1TB NVMe drive for music storage and have a more-or-less instant LMS server in the same form-factor as a Pi4B with a whole lot more...

They may have been rolling their own OPTs in the 90s, but now they use Edcor (hard to miss those blue bobbins). Again, not a problem - Edcor makes good iron - but it implies that perhaps the whole may be a fair bit more expensive than the sum of its parts.

Mine arrived as well. Thanks, Joe!

I have one quite similar that belonged to my great grandfather. I'll take some photos.

There's nothing special about the standard Zen Triode these days. They use Edcor iron (nothing special there - just good, solid, American-made iron), and a relatively unsophisticated (but reliable) circuit. Running the SEPs as triode-strapped may make them sweeter-sounding, but seriously chops...

To be clear, I have LMS running on an 8-core Atom server running Windows Server 2016 Essentials. YMMV running it on a Pi4.

Very much so. I'm running an LMS back-end with six Moode endpoints currently.

I'm with Roscoe - if the CHBs sound good (albeit bass-shy), then perhaps the answer is to go with the CHBs + sub (and maybe down the line a super-tweeter if you are so inclined) and save the Alpairs for a different cabinet.

Yep. Although it seems eBay is the only place to find OPA2604 op-amps now. :(

I have been tempted by something like that (actually, I'm tempted by an AD1865 Pi hat, but can't afford right now), although in theory, I could just plug this Magnavox via SPDIF into my current GDA-600. However, I figured I'd try it out au natural for a while first (albeit with some strategic...
