Queue the peanut gallery please! Just thought I would share with you my latest experiments. Warming up in the batter's cage I have a pair of the most rare and almost completely unknown Duelund Precision Bypass capacitors in the 600V, 0.047uF size.

Technically Silver Foil in Wax/Oil only four sizes are available:

600V

=====

0.01uF

0.022uF

0.047uF (measured 0.0475 and 0.0476)

0.1uF

Measured ESR, DF and Q were all below measurement thresholds of my DATS V2.

Back Story

Very few of these have been produced so far. With a retail price around $4,000 / uF they certainly rank among the most expensive caps money can buy.

Hand made in Denmark by blind virgins who were raised in a convent and never been allowed to listen to Michale Buble or Justin Timberlake.

The Spaniards melted down the silver at a temple dedicated to Tlaloc, the Aztec god of Thunder. Shortly after loading the silver onto the galleon the Esmeralda, the ship set sail for Cuba. Before it could reach the horizon out of a calm but cloudy day a wind gust turned the ship almost completely around and that's when lightning hit all four of it's masts simultaneously. The ship was set afire like a four ended candelabra in the sunset. The silver used in the Precision Bypass caps comes exclusively from that wreckage, and when that supply is gone there will be no more.

OK, I'm making that up, but that's the kind of back-story caps this expensive should have. They really are pretty rare though.

I'll be using this to bypass the Clarity MR 400V, 4.7uF caps in my tweeter crossover. Previously I had a 0.1uF Audyn True Copper capacitor, which ended up being too bright. I'm still using that cap but elsewhere.

So, to the peanut gallery, just cut and paste your usual comments please, don't bother typing in something original or new.

We'll see how long it takes me to list these caps on E-bay.
