I'm working on v2 of the Pete Millet mic preamp. I've had the parts to mostly finish it for about a year, but kept it on the shelf for no good reasons. But I've needed to do something to take my mind off the stress of these last few months so I took it off the shelf.

Both main PCBs (the yellow ones) are "permanently" mounted, and I mounted the female input XLR's. I also wired them to the inputs of both boards. It's coming along slowly but surely.

The image is a collage of two photographs taken from different angles, showcasing an industrial setting with pipes and valves.

In the upper photograph, we see an overhead view of the room where multiple metal pipes are running along the ceiling. These pipes have various valves attached to them at intervals. The pipe arrangement suggests a complex system or network, possibly for transporting water or other fluids.

The lower photograph offers a ground-level perspective, allowing us to see more details of the room's structure. It shows a concrete floor supporting the weight of the pipes and valves above. The layout of the piping suggests it might be part of an industrial setup, possibly for manufacturing or processing purposes.

Both photos are in black and white, which gives them a slightly nostalgic feel. There is no visible text within the image to provide additional context or information.

Subject: complaint about cargo-culting audiophools and the #marketers that exploit them

I saw a new #scam yesterday. Well, new to me. It's probably been around forever.

There are many, many #fraudulent products and ideas out there that target the self-described "audiophiles". And because such #audiophools never do double-blind tests, they always convince themselves of just how well the #scammy products work ("you are the easiest person for you to fool").

Examples of long standing:

Super-thick "oxygen-free copper" #cables for #speakers or #interconnects, being sold at 100x the price of regular cables.

Electrically shielded fiber-optic cables (!).

Paint pens to colour in the outer edge of CDs and DVDs.

Systems to run your equipment from #batteries so as not to contaminate them with that dirty mains #AC.

#Tubes / #valves instead of solid-state #amplification.

... and on and on.

Well, yesterday I was looking for some opamps (tiny little chips, used everywhere), and came across a place selling replacement #opamps for use inside stereo equipment. You can get perfectly good designed-for-audio opamps of good quality for a few bucks each. Upgrading your equipment to better opamps sometimes made sense in the 1970s, but not now. The ones used from the factory are fine.

But no, this one was selling fancy opamps, designed for *RF* use, not audio, which normally cost $10-20 each, in fancy little metal packages, for hundreds of dollars apiece.

"A fool and his money ..."
